WEBVTT

00:00:23.219 --> 00:00:25.618
<v Wojciech Wegrzynski>Everybody welcome to the fire science show today.

00:00:25.618 --> 00:00:27.868
<v Wojciech Wegrzynski>Broadcasting from Brno in Czech Republic.

00:00:28.289 --> 00:00:30.239
<v Wojciech Wegrzynski>Together with my friends and colleagues.

00:00:30.268 --> 00:00:30.958
<v Wojciech Wegrzynski>Douglas Kresky.

00:00:31.199 --> 00:00:33.448
<v Wojciech Wegrzynski>At fam tech conference aggregators.

00:00:33.503 --> 00:00:34.643
<v Grzegorz Krajewski>Hello, welcome everybody.

00:00:34.734 --> 00:00:38.005
<v Wojciech Wegrzynski>Great to have you in the show and, uh, We came here.

00:00:38.005 --> 00:00:46.494
<v Wojciech Wegrzynski>we We're having a local tourne hour around Europe sharing the preliminary research of our new, fascinating project.

00:00:46.494 --> 00:00:48.984
<v Wojciech Wegrzynski>And we thought that it may be great to share it.

00:00:49.554 --> 00:00:51.104
<v Wojciech Wegrzynski>With you, what do you think Chickasha?

00:00:51.655 --> 00:00:52.225
<v Grzegorz Krajewski>I think it's.

00:00:52.344 --> 00:00:56.064
<v Grzegorz Krajewski>Generally a great idea because it's project starts three years, so he's fine.

00:00:56.125 --> 00:00:57.384
<v Grzegorz Krajewski>A moment to show it to the

00:00:57.784 --> 00:01:01.972
<v Wojciech Wegrzynski>I usually have said that it's like, it's going Like scheduled rides.

00:01:02.075 --> 00:01:03.935
<v Wojciech Wegrzynski>It's not that we've spent like three years building.

00:01:03.935 --> 00:01:06.724
<v Wojciech Wegrzynski>it now, actually, actually we did, but we're very happy to.

00:01:06.834 --> 00:01:10.305
<v Wojciech Wegrzynski>Have completed stage one or something that we call stage one of the project.

00:01:10.334 --> 00:01:16.731
<v Wojciech Wegrzynski>It was a big, big advancement in, building a new facility for small controlling in corridors.

00:01:16.852 --> 00:01:21.531
<v Wojciech Wegrzynski>The project name is Jaeger's we're horrible at naming projects.

00:01:21.849 --> 00:01:22.959
<v Grzegorz Krajewski>But it's an official name.

00:01:22.989 --> 00:01:24.998
<v Grzegorz Krajewski>We'd have to find out something new.

00:01:25.239 --> 00:01:25.418
<v Wojciech Wegrzynski>Yeah.

00:01:25.478 --> 00:01:32.228
<v Wojciech Wegrzynski>Well, if just someone in the audience has a proposal, how to call the sexy project, please let us know because we certainly fail at doing that.

00:01:32.799 --> 00:01:33.259
<v Wojciech Wegrzynski>Unfortunately.

00:01:34.091 --> 00:01:38.597
<v Wojciech Wegrzynski>Anyway, uh, The project is on the smoke control in corridors.

00:01:38.628 --> 00:01:40.697
<v Wojciech Wegrzynski>And I think it's a really interesting.

00:01:40.757 --> 00:01:43.608
<v Wojciech Wegrzynski>A topic that's very, very worthy of.

00:01:43.658 --> 00:01:44.268
<v Wojciech Wegrzynski>Investigation.

00:01:45.248 --> 00:01:45.768
<v Wojciech Wegrzynski>And.

00:01:46.012 --> 00:01:49.432
<v Wojciech Wegrzynski>It's something that consists of two separate parts parts.

00:01:49.462 --> 00:01:55.370
<v Wojciech Wegrzynski>One would be in the new, how we call it next generation experimental facility for.

00:01:55.432 --> 00:01:57.081
<v Wojciech Wegrzynski>Investigation of smoke controls.

00:01:57.081 --> 00:02:00.162
<v Wojciech Wegrzynski>And this is something that Jaeger's was leading for the last three years.

00:02:00.831 --> 00:02:14.086
<v Wojciech Wegrzynski>And part two is something that was more on my shoulders, which is the digital twin of this facility, which is a fancy name for a numerical Simulator of the exact same experiments we do in the facility.

00:02:14.391 --> 00:02:18.831
<v Wojciech Wegrzynski>I want to say is an ethics degeneration and experimental facility for investigation of smoke control.

00:02:18.831 --> 00:02:21.741
<v Wojciech Wegrzynski>Doesn't really give you an impression of what it is.

00:02:21.741 --> 00:02:22.282
<v Wojciech Wegrzynski>So it's all jokes.

00:02:22.342 --> 00:02:25.192
<v Wojciech Wegrzynski>Please tell the listeners what we have actually built in punky.

00:02:25.784 --> 00:02:30.525
<v Grzegorz Krajewski>we built 40 meters long corridor with height of three meters and variable.

00:02:31.227 --> 00:02:31.706
<v Grzegorz Krajewski>or floor.

00:02:31.736 --> 00:02:33.387
<v Grzegorz Krajewski>So it's a very fixable.

00:02:33.990 --> 00:02:38.569
<v Grzegorz Krajewski>the white of corridor is 1.4 meters and to corridor is.

00:02:38.599 --> 00:02:41.469
<v Grzegorz Krajewski>equipped with fully flexible ventilation system.

00:02:41.917 --> 00:02:44.276
<v Grzegorz Krajewski>system, which allows us to test.

00:02:44.473 --> 00:02:48.554
<v Grzegorz Krajewski>Probably most of possible ventilation combinations.

00:02:48.963 --> 00:02:51.274
<v Wojciech Wegrzynski>It's kind of interesting when you think about this.

00:02:51.514 --> 00:02:52.304
<v Wojciech Wegrzynski>It's just a corridor.

00:02:53.223 --> 00:02:57.804
<v Wojciech Wegrzynski>But the facility like that has, I have never seen a thing like that in my life.

00:02:58.163 --> 00:03:00.593
<v Wojciech Wegrzynski>we've always only seen the research and the corridors.

00:03:00.623 --> 00:03:09.354
<v Wojciech Wegrzynski>This was done at Hawk at some buildings, and it was just limited, limited, limited studies that just investigated one parameter, two perimeters, or just few parameters.

00:03:09.804 --> 00:03:17.153
<v Wojciech Wegrzynski>Uh, and here we've built a facility that Is bespoke engineered to really facilitate multiple variants of fire.

00:03:17.213 --> 00:03:18.174
<v Wojciech Wegrzynski>Uh, research in it.

00:03:18.234 --> 00:03:24.794
<v Wojciech Wegrzynski>And, uh, I think it's, it's beautiful because the possibilities are endless for something such as small as.

00:03:24.939 --> 00:03:26.219
<v Wojciech Wegrzynski>It's just a corridor.

00:03:27.669 --> 00:03:29.800
<v Wojciech Wegrzynski>Uh, let's talk why we build it.

00:03:29.800 --> 00:03:31.259
<v Wojciech Wegrzynski>I think I think.

00:03:31.669 --> 00:03:36.024
<v Wojciech Wegrzynski>And then maybe even more important widen then how we build it.

00:03:36.311 --> 00:03:36.870
<v Wojciech Wegrzynski>For me, myself.

00:03:37.699 --> 00:03:41.370
<v Wojciech Wegrzynski>You know, when you look into statistics, when you look into.

00:03:42.080 --> 00:03:44.479
<v Wojciech Wegrzynski>The main causes of death in fires.

00:03:44.930 --> 00:03:49.629
<v Wojciech Wegrzynski>Obviously the smoke inhalation always pops up as the, as the number one We.

00:03:49.866 --> 00:03:50.537
<v Wojciech Wegrzynski>Observe.

00:03:50.717 --> 00:03:57.706
<v Wojciech Wegrzynski>deadly fires in residential buildings in which the smoke spreads through evacuation pathways.

00:03:57.766 --> 00:04:02.304
<v Wojciech Wegrzynski>Uh, has threatened people outside of the, compartment of origin, of the fires.

00:04:02.334 --> 00:04:04.193
<v Wojciech Wegrzynski>And for me, these are very.

00:04:04.431 --> 00:04:06.370
<v Wojciech Wegrzynski>Difficult fights, dangerous fires.

00:04:06.764 --> 00:04:08.503
<v Wojciech Wegrzynski>I mean, if I set the fire in my own.

00:04:08.924 --> 00:04:11.894
<v Wojciech Wegrzynski>If I'm in my own living room, I guess I can live with that.

00:04:11.894 --> 00:04:15.614
<v Wojciech Wegrzynski>But if my neighbor does and I'm in danger, this is a pretty bad.

00:04:15.913 --> 00:04:16.704
<v Wojciech Wegrzynski>Station for myself.

00:04:17.324 --> 00:04:20.204
<v Wojciech Wegrzynski>So definitely I feel there is a need to.

00:04:20.803 --> 00:04:23.384
<v Wojciech Wegrzynski>Understand how smoke in the horizontal.

00:04:23.744 --> 00:04:25.634
<v Wojciech Wegrzynski>Evacuation roads travel.

00:04:25.663 --> 00:04:26.713
<v Wojciech Wegrzynski>What's happening with it.

00:04:26.774 --> 00:04:28.064
<v Wojciech Wegrzynski>And how can we extract it?

00:04:28.483 --> 00:04:29.024
<v Wojciech Wegrzynski>What.

00:04:29.444 --> 00:04:30.858
<v Wojciech Wegrzynski>Can we do with it?

00:04:31.237 --> 00:04:35.166
<v Wojciech Wegrzynski>For you, what was the rationale when you propose to the, this research?

00:04:35.797 --> 00:04:40.117
<v Wojciech Wegrzynski>What's what's in your mind when you've started pursuing this project.

00:04:40.216 --> 00:04:40.786
<v Grzegorz Krajewski>As you remember.

00:04:40.817 --> 00:04:47.557
<v Grzegorz Krajewski>we are, involved in many commissioning testing in residential buildings, in, hotel building some kind of, , public arenas.

00:04:47.916 --> 00:04:48.997
<v Grzegorz Krajewski>And there were a lot of corridors.

00:04:49.596 --> 00:04:51.067
<v Grzegorz Krajewski>The problem is corridor is dead.

00:04:51.127 --> 00:04:53.024
<v Grzegorz Krajewski>It's dramatically small space.

00:04:53.024 --> 00:04:55.603
<v Grzegorz Krajewski>So when you've got a fire, The smoke.

00:04:55.620 --> 00:04:59.009
<v Grzegorz Krajewski>Jay is spreading so quickly along the corridor.

00:04:59.040 --> 00:05:02.853
<v Grzegorz Krajewski>That's the time for evacuation and, to, for, firefighters.

00:05:03.434 --> 00:05:05.514
<v Grzegorz Krajewski>Um, is going to be, to be very sure.

00:05:05.514 --> 00:05:10.423
<v Grzegorz Krajewski>So I think that was the main reason why I decided to take care about the topic.

00:05:10.454 --> 00:05:14.593
<v Grzegorz Krajewski>And the second part was the cooperation with the pressure differential system.

00:05:14.867 --> 00:05:19.757
<v Grzegorz Krajewski>So, so I found it think it was the main reason I sent it to is connected with my muster science.

00:05:20.516 --> 00:05:21.387
<v Wojciech Wegrzynski>Yeah, that's cool.

00:05:21.387 --> 00:05:25.916
<v Wojciech Wegrzynski>I think the interaction between Is something we very, very rarely.

00:05:25.966 --> 00:05:31.276
<v Wojciech Wegrzynski>understand well, if we, even the revenue model that we even readily take that into account.

00:05:31.276 --> 00:05:34.757
<v Wojciech Wegrzynski>When we design smoke control systems in our buildings and.

00:05:35.326 --> 00:05:35.956
<v Wojciech Wegrzynski>Certainly.

00:05:36.047 --> 00:05:43.129
<v Wojciech Wegrzynski>I remember that the time when we were And We had this very, very powerful pressurization systems in the corridors.

00:05:43.754 --> 00:05:48.223
<v Wojciech Wegrzynski>in the staircases that connected to corridors, we were doing called smoke tests in compartments.

00:05:48.254 --> 00:05:48.824
<v Wojciech Wegrzynski>Next to that corridor.

00:05:49.694 --> 00:05:52.423
<v Wojciech Wegrzynski>We had this very beautiful smoke layer.

00:05:52.994 --> 00:05:54.434
<v Wojciech Wegrzynski>A good extraction system.

00:05:54.434 --> 00:05:56.744
<v Wojciech Wegrzynski>Everything was working as it was supposed to.

00:05:57.074 --> 00:05:59.829
<v Wojciech Wegrzynski>And then bam, someone opens the door, high velocity flow.

00:05:59.980 --> 00:06:05.800
<v Wojciech Wegrzynski>It gets into the corridor and suddenly don't have a layer everything's mixed around.

00:06:05.800 --> 00:06:08.529
<v Wojciech Wegrzynski>And I mean, the smoke control was designed as it should.

00:06:08.560 --> 00:06:10.480
<v Wojciech Wegrzynski>The PDs was designed as it should.

00:06:10.480 --> 00:06:15.579
<v Wojciech Wegrzynski>It's just, they were not designed It's uh, I think there, the observation is, is very spot

00:06:16.300 --> 00:06:17.230
<v Grzegorz Krajewski>The same thing is happening.

00:06:17.259 --> 00:06:18.910
<v Grzegorz Krajewski>on every, every construction workers.

00:06:18.910 --> 00:06:21.040
<v Grzegorz Krajewski>mine is working properly, but no money is looking.

00:06:21.399 --> 00:06:22.870
<v Grzegorz Krajewski>on that in the overall project.

00:06:22.870 --> 00:06:23.220
<v Grzegorz Krajewski>Yes.

00:06:23.502 --> 00:06:28.093
<v Grzegorz Krajewski>So, so it works like That last time we were in an office building and it was the same situation.

00:06:28.093 --> 00:06:35.480
<v Grzegorz Krajewski>So that's the reason why we are taking care about the topic What we are going to test and what we are going to.

00:06:35.927 --> 00:06:36.908
<v Grzegorz Krajewski>From these tests.

00:06:37.363 --> 00:06:38.750
<v Wojciech Wegrzynski>And, in, in the sports arenas.

00:06:39.329 --> 00:06:40.629
<v Wojciech Wegrzynski>The corridors are huge.

00:06:40.689 --> 00:06:42.439
<v Wojciech Wegrzynski>They can accommodate a lot of smoke, but you've mentioned.

00:06:42.879 --> 00:06:43.639
<v Wojciech Wegrzynski>In residential buildings.

00:06:43.839 --> 00:06:44.500
<v Wojciech Wegrzynski>They're like tiny,

00:06:44.557 --> 00:06:45.331
<v Grzegorz Krajewski>Tiny small.

00:06:45.396 --> 00:06:48.846
<v Grzegorz Krajewski>So-so the time for, to fulfill with the smoke is very, very short.

00:06:49.177 --> 00:06:49.713
<v Wojciech Wegrzynski>Exactly.

00:06:49.713 --> 00:06:54.204
<v Wojciech Wegrzynski>for, for me also, when we started doing that, because a significant aspect of this.

00:06:54.473 --> 00:06:58.353
<v Wojciech Wegrzynski>After this project is to be able to simulate different scenarios.

00:06:59.274 --> 00:07:03.113
<v Wojciech Wegrzynski>And I don't only mean the scenario of operation of the smoke ventilation system.

00:07:03.113 --> 00:07:08.603
<v Wojciech Wegrzynski>Like the world exhaust capacity we have or where the inlets are located, but you know, the whole.

00:07:09.204 --> 00:07:12.834
<v Wojciech Wegrzynski>the whole idea of what happens when the fire starts.

00:07:13.134 --> 00:07:16.434
<v Wojciech Wegrzynski>I remember what that was many, many years ago when I was doing.

00:07:16.913 --> 00:07:19.103
<v Wojciech Wegrzynski>My master thesis, I was doing a corridor.

00:07:19.266 --> 00:07:22.476
<v Wojciech Wegrzynski>In that disease is it's quite funny because at that point I had.

00:07:23.007 --> 00:07:32.456
<v Wojciech Wegrzynski>Really really low amount of knowledge on smoke control systems because it's, it was not something I would, uh, actively pursue during my studies.

00:07:32.456 --> 00:07:34.976
<v Wojciech Wegrzynski>I was more interested in detection and suppression.

00:07:35.516 --> 00:07:39.146
<v Wojciech Wegrzynski>Smoke control is not, not in the focal point back then, which is funny essay.

00:07:39.596 --> 00:07:41.156
<v Wojciech Wegrzynski>Um, that was smoke control engineer.

00:07:41.584 --> 00:07:41.704
<v Wojciech Wegrzynski>and.

00:07:41.704 --> 00:07:42.874
<v Wojciech Wegrzynski>my master thesis, I thought, okay.

00:07:42.903 --> 00:07:44.387
<v Wojciech Wegrzynski>I'll need to show some simulations.

00:07:44.387 --> 00:07:47.447
<v Wojciech Wegrzynski>I wanted to, to show the, the modern tools of fire safety engineering.

00:07:47.476 --> 00:07:48.797
<v Wojciech Wegrzynski>how they play together.

00:07:49.067 --> 00:07:50.627
<v Wojciech Wegrzynski>And I was doing a simulation of.

00:07:50.687 --> 00:07:53.427
<v Wojciech Wegrzynski>a fire in a compartment next to a 30 meter corridor.

00:07:53.867 --> 00:07:55.487
<v Wojciech Wegrzynski>Surprise surprise the same way we just built.

00:07:55.757 --> 00:07:57.689
<v Wojciech Wegrzynski>Uh, what the Kings students and, Yeah.

00:07:57.810 --> 00:08:01.339
<v Wojciech Wegrzynski>And in, in that simulations, It's just, you know, started the fire in the compartment.

00:08:01.903 --> 00:08:03.673
<v Wojciech Wegrzynski>I opened the door to the corridor.

00:08:03.944 --> 00:08:05.653
<v Wojciech Wegrzynski>The smoke flows to the corridor and.

00:08:06.343 --> 00:08:10.124
<v Wojciech Wegrzynski>There's nothing I can tell you that It just feels my corridor like completely.

00:08:10.394 --> 00:08:12.673
<v Wojciech Wegrzynski>I have like one minute of evacuation time.

00:08:12.673 --> 00:08:15.074
<v Wojciech Wegrzynski>There's no, there's literally no, nothing I can do about it.

00:08:15.374 --> 00:08:17.713
<v Wojciech Wegrzynski>I increase the smoke system capacity.

00:08:17.774 --> 00:08:18.494
<v Wojciech Wegrzynski>Doesn't help.

00:08:18.853 --> 00:08:20.863
<v Wojciech Wegrzynski>I put more in this doesn't really help.

00:08:20.894 --> 00:08:23.074
<v Wojciech Wegrzynski>I then approached you at one of the senior colleagues.

00:08:23.497 --> 00:08:27.156
<v Wojciech Wegrzynski>I showed them my CFD and say, You see, I have a problem.

00:08:27.156 --> 00:08:28.057
<v Wojciech Wegrzynski>It doesn't work.

00:08:28.057 --> 00:08:29.947
<v Wojciech Wegrzynski>And he's like, yeah, obviously it doesn't work.

00:08:29.976 --> 00:08:30.997
<v Wojciech Wegrzynski>You didn't shut the door.

00:08:31.357 --> 00:08:34.147
<v Wojciech Wegrzynski>And I'm like, oh, That's how you do that.

00:08:34.236 --> 00:08:36.346
<v Wojciech Wegrzynski>I found it really Grazie that.

00:08:36.964 --> 00:08:44.974
<v Wojciech Wegrzynski>the scenario of the system in this case, shutting the door after some time was the only way I could prove the system is working.

00:08:44.974 --> 00:08:46.833
<v Wojciech Wegrzynski>And I don't think I proved the system is work.

00:08:46.833 --> 00:08:47.063
<v Wojciech Wegrzynski>I proved.

00:08:47.734 --> 00:08:48.663
<v Wojciech Wegrzynski>That by shutting the door.

00:08:48.663 --> 00:08:51.183
<v Wojciech Wegrzynski>I don't have smoke on my corridor anymore.

00:08:51.214 --> 00:08:54.364
<v Wojciech Wegrzynski>And the more I've worked with this solutions.

00:08:54.543 --> 00:08:56.364
<v Wojciech Wegrzynski>The the more I observed.

00:08:56.573 --> 00:08:58.464
<v Wojciech Wegrzynski>In a way it is reality of the design.

00:08:58.894 --> 00:09:01.553
<v Grzegorz Krajewski>And this is exactly that what you said yesterday during her presentation.

00:09:02.244 --> 00:09:04.734
<v Grzegorz Krajewski>If you, you just have to be a smart, smart engineer.

00:09:04.734 --> 00:09:05.033
<v Grzegorz Krajewski>Yes.

00:09:05.364 --> 00:09:07.854
<v Grzegorz Krajewski>You are closing the door and see your system is working properly.

00:09:08.303 --> 00:09:09.083
<v Grzegorz Krajewski>because you don't have.

00:09:09.083 --> 00:09:10.644
<v Grzegorz Krajewski>any source of smoking.

00:09:11.004 --> 00:09:11.394
<v Grzegorz Krajewski>And heat

00:09:11.594 --> 00:09:15.677
<v Wojciech Wegrzynski>And,  As we were starting the project as we were building our knowledge.

00:09:15.705 --> 00:09:19.427
<v Wojciech Wegrzynski>on the context of the systems that we want to investigate.

00:09:19.736 --> 00:09:28.352
<v Wojciech Wegrzynski>I guess we very quickly realized that this scenario on how you model, how you test, how you validate your solution.

00:09:28.659 --> 00:09:30.090
<v Wojciech Wegrzynski>Is very.

00:09:30.500 --> 00:09:36.259
<v Wojciech Wegrzynski>Conscious specific, like in Poland, we do it in a certain In the UK, they do it in a completely different way in Germany.

00:09:36.259 --> 00:09:37.429
<v Wojciech Wegrzynski>They do it in a different way.

00:09:37.909 --> 00:09:40.429
<v Wojciech Wegrzynski>In many of these cases, you either have a prescribed.

00:09:40.928 --> 00:09:46.076
<v Wojciech Wegrzynski>He released rates, smoke, suit, yield, and other parameters of your fire that you want to model.

00:09:46.437 --> 00:09:53.076
<v Wojciech Wegrzynski>And based on these parameters, you have some acceptance criteria to which you refer, and then you say your system works.

00:09:53.697 --> 00:09:54.177
<v Wojciech Wegrzynski>In the UK.

00:09:54.206 --> 00:09:58.277
<v Wojciech Wegrzynski>I believe they, they had this funny scenarios where they shut the doors and open the doors.

00:09:59.226 --> 00:09:59.527
<v Grzegorz Krajewski>Right.

00:09:59.886 --> 00:10:05.586
<v Grzegorz Krajewski>In that point, we are very thankful to track on the Wallace who explain us how the.

00:10:06.067 --> 00:10:11.496
<v Grzegorz Krajewski>UK British tonight are working with opening and closing the doors on their timeline.

00:10:11.864 --> 00:10:13.874
<v Grzegorz Krajewski>But Coming back to your sentence, which you said.

00:10:14.268 --> 00:10:17.298
<v Grzegorz Krajewski>There is a lack of information about that.

00:10:17.748 --> 00:10:20.327
<v Grzegorz Krajewski>What is happening in a full-scale corridor?

00:10:20.357 --> 00:10:20.687
<v Grzegorz Krajewski>Yes.

00:10:21.138 --> 00:10:25.374
<v Grzegorz Krajewski>At the beginning of the project, we're thinking of making some kind of a scale model.

00:10:25.374 --> 00:10:25.854
<v Grzegorz Krajewski>. But to.

00:10:26.274 --> 00:10:31.043
<v Grzegorz Krajewski>When we started to read the literature, the lack of information was so big.

00:10:31.073 --> 00:10:33.533
<v Grzegorz Krajewski>There is a one big black hole about in that topic.

00:10:33.563 --> 00:10:36.913
<v Grzegorz Krajewski>So the last tests were made, I think, 20 years ago or more.

00:10:37.644 --> 00:10:43.443
<v Grzegorz Krajewski>So that's why we decided to extend the project and to make the full scale corridor.

00:10:44.043 --> 00:10:50.943
<v Grzegorz Krajewski>And that's what we have now, after the first test, the results Totally different than, than we expected at the

00:10:51.673 --> 00:10:54.058
<v Wojciech Wegrzynski>Yeah, I think it was a good idea too, to make it full-scale.

00:10:54.089 --> 00:10:55.859
<v Wojciech Wegrzynski>I mean, it's going to be easier to publish and all right.

00:10:57.149 --> 00:10:58.979
<v Wojciech Wegrzynski>Maybe it makes us, it makes us.

00:10:59.038 --> 00:11:00.009
<v Wojciech Wegrzynski>Our work as scientists.

00:11:00.389 --> 00:11:03.208
<v Wojciech Wegrzynski>So much easier when you have full scaling, then I'll have justified the scaling factors.

00:11:03.899 --> 00:11:07.318
<v Wojciech Wegrzynski>But outside of that, I think it is important to.

00:11:07.798 --> 00:11:09.957
<v Wojciech Wegrzynski>Establishing new zero.

00:11:10.018 --> 00:11:15.941
<v Wojciech Wegrzynski>I call it the new north star, you S we have to rely on tricks on scenarios in.

00:11:16.451 --> 00:11:17.181
<v Wojciech Wegrzynski>Estimating.

00:11:17.620 --> 00:11:18.380
<v Wojciech Wegrzynski>Smoke control performance.

00:11:19.181 --> 00:11:21.880
<v Wojciech Wegrzynski>And I'm not saying we design systems that are bad.

00:11:22.270 --> 00:11:24.071
<v Wojciech Wegrzynski>That's not necessarily the case.

00:11:24.130 --> 00:11:24.880
<v Wojciech Wegrzynski>I'm just saying.

00:11:25.150 --> 00:11:29.530
<v Wojciech Wegrzynski>We designed them in the stupid way where we have no idea what the performance is.

00:11:29.860 --> 00:11:31.880
<v Wojciech Wegrzynski>We have established some sort of.

00:11:32.460 --> 00:11:33.330
<v Wojciech Wegrzynski>Tests of.

00:11:33.455 --> 00:11:35.075
<v Wojciech Wegrzynski>validation method.

00:11:35.434 --> 00:11:46.163
<v Wojciech Wegrzynski>It's extremely artificial and that, Only informs you of how the system ranks again, this, the test, but it does not inform you on what safety does it provide in a building.

00:11:46.763 --> 00:11:54.245
<v Wojciech Wegrzynski>And if you are all into ASET/RSET calculations, if you're all into just fulfilling the standard needs.

00:11:55.205 --> 00:11:57.274
<v Wojciech Wegrzynski>I guess you can leave with that.

00:11:57.274 --> 00:12:00.121
<v Wojciech Wegrzynski>If, these standard, if this level of safety.

00:12:00.451 --> 00:12:01.231
<v Wojciech Wegrzynski>This implicit.

00:12:01.322 --> 00:12:04.022
<v Wojciech Wegrzynski>Level of safety hidden within these assumptions.

00:12:04.022 --> 00:12:05.261
<v Wojciech Wegrzynski>If that's what you aim for.

00:12:05.701 --> 00:12:05.881
<v Wojciech Wegrzynski>Yeah.

00:12:05.912 --> 00:12:06.241
<v Wojciech Wegrzynski>Cool.

00:12:06.302 --> 00:12:07.322
<v Wojciech Wegrzynski>You can design it like that.

00:12:07.861 --> 00:12:09.562
<v Wojciech Wegrzynski>But if you truly want to understand.

00:12:09.841 --> 00:12:14.284
<v Wojciech Wegrzynski>How your system What do you gain by putting the system?

00:12:14.725 --> 00:12:16.014
<v Wojciech Wegrzynski>How the system will behave.

00:12:16.014 --> 00:12:18.485
<v Wojciech Wegrzynski>Your fire scenario is slightly different.

00:12:19.011 --> 00:12:23.442
<v Wojciech Wegrzynski>You have no way to know that today with the current models and we don't have good.

00:12:24.231 --> 00:12:27.261
<v Wojciech Wegrzynski>Experimental proof on how these things work.

00:12:27.491 --> 00:12:28.664
<v Grzegorz Krajewski>This is the point, what you said.

00:12:28.695 --> 00:12:28.934
<v Grzegorz Krajewski>Yes.

00:12:28.934 --> 00:12:30.284
<v Grzegorz Krajewski>It's time for effort.

00:12:31.485 --> 00:12:36.392
<v Grzegorz Krajewski>To come back To the fundamentals  of the small problem is just, just want to pick out.

00:12:36.721 --> 00:12:37.451
<v Grzegorz Krajewski>Compartment.

00:12:37.892 --> 00:12:39.302
<v Grzegorz Krajewski>Adjustment to the corridor.

00:12:39.392 --> 00:12:40.351
<v Grzegorz Krajewski>Very simple.

00:12:40.501 --> 00:12:42.309
<v Grzegorz Krajewski>It's it looks like a very simple topic.

00:12:42.337 --> 00:12:42.577
<v Grzegorz Krajewski>But.

00:12:42.772 --> 00:12:43.761
<v Grzegorz Krajewski>as we can see here.

00:12:44.422 --> 00:12:45.032
<v Grzegorz Krajewski>She said yes.

00:12:45.412 --> 00:12:47.091
<v Grzegorz Krajewski>Because so many variables.

00:12:47.611 --> 00:12:49.368
<v Grzegorz Krajewski>which we have to, predict.

00:12:50.067 --> 00:12:52.977
<v Grzegorz Krajewski>We have to check how, how system is going to work.

00:12:53.008 --> 00:12:58.779
<v Grzegorz Krajewski>We have to, verify and check the environmental conditions in the corridor, which we still accept.

00:12:59.018 --> 00:13:02.048
<v Grzegorz Krajewski>We probably will never have got the perfect conditions.

00:13:02.375 --> 00:13:06.125
<v Grzegorz Krajewski>But we have to find the moment when that conditions are acceptable for us.

00:13:06.514 --> 00:13:08.288
<v Grzegorz Krajewski>And for people who are, evacuating.

00:13:08.438 --> 00:13:08.644
<v Grzegorz Krajewski>during

00:13:09.575 --> 00:13:10.264
<v Wojciech Wegrzynski>So, , okay.

00:13:10.264 --> 00:13:18.125
<v Wojciech Wegrzynski>We have the facility now We, we hope to do this restart to find the new north star of smoke control in corridors.

00:13:18.125 --> 00:13:24.721
<v Wojciech Wegrzynski>Give you a benchmark against a, the solutions can be tested And we truly hope to achieve that.

00:13:24.721 --> 00:13:26.707
<v Wojciech Wegrzynski>It's a, ambitious, ambitious goal.

00:13:26.977 --> 00:13:29.347
<v Wojciech Wegrzynski>Now let's talk about the facility.

00:13:29.347 --> 00:13:33.217
<v Wojciech Wegrzynski>I mean, yesterday during my talk, there was already a lot of questions.

00:13:33.217 --> 00:13:35.427
<v Wojciech Wegrzynski>Ask about technical details, how the facility.

00:13:35.798 --> 00:13:36.937
<v Wojciech Wegrzynski>Whereas, how does it operate?

00:13:36.937 --> 00:13:37.717
<v Wojciech Wegrzynski>How does it look like?

00:13:37.778 --> 00:13:41.798
<v Wojciech Wegrzynski>Um, unfortunately I don't see the pictures, but it does exist.

00:13:41.857 --> 00:13:43.087
<v Wojciech Wegrzynski>It's it's beautiful.

00:13:43.087 --> 00:13:43.827
<v Wojciech Wegrzynski>I, we love it.

00:13:44.312 --> 00:13:44.611
<v Wojciech Wegrzynski>Anyway.

00:13:44.942 --> 00:13:48.721
<v Wojciech Wegrzynski>Let's let's talk a little about technicalities of what we have built.

00:13:48.721 --> 00:13:53.642
<v Wojciech Wegrzynski>So you've said it's a 30 meter long corridor, but that doesn't give her the whole story.

00:13:53.822 --> 00:13:54.567
<v Wojciech Wegrzynski>I stir.

00:13:54.601 --> 00:13:55.152
<v Wojciech Wegrzynski>Are things.

00:13:55.741 --> 00:13:56.351
<v Wojciech Wegrzynski>Connected to that.

00:13:56.642 --> 00:13:57.552
<v Wojciech Wegrzynski>Like first, the compartments.

00:13:57.865 --> 00:13:58.748
<v Grzegorz Krajewski>as what you said, this.

00:13:59.677 --> 00:14:01.927
<v Grzegorz Krajewski>Cory door and there are free compartments.

00:14:02.288 --> 00:14:03.817
<v Grzegorz Krajewski>Uh, adjustment to that corridor.

00:14:04.177 --> 00:14:06.028
<v Grzegorz Krajewski>Each one is free by four meters.

00:14:06.562 --> 00:14:08.662
<v Grzegorz Krajewski>floor Aria and hide three meters.

00:14:08.991 --> 00:14:09.751
<v Grzegorz Krajewski>So we can.

00:14:10.522 --> 00:14:14.001
<v Grzegorz Krajewski>we have got a huge flexibility of locating the fire source.

00:14:14.032 --> 00:14:17.251
<v Grzegorz Krajewski>We can look at it in the middle or at the beginning or at the end of the corridor.

00:14:18.134 --> 00:14:18.315
<v Grzegorz Krajewski>so.

00:14:18.825 --> 00:14:21.674
<v Grzegorz Krajewski>As you can see, we've got just three variables at the beginning.

00:14:21.764 --> 00:14:24.315
<v Grzegorz Krajewski>Yes, we can locate the fire inside the corridor.

00:14:24.735 --> 00:14:26.205
<v Grzegorz Krajewski>In any position?

00:14:26.955 --> 00:14:27.595
<v Grzegorz Krajewski>Where we want.

00:14:28.245 --> 00:14:34.652
<v Grzegorz Krajewski>Additionally, this is the only the geometry Galleria and Another font is he trees rate of the fires.

00:14:34.831 --> 00:14:39.942
<v Grzegorz Krajewski>So I think we can multiple every, every possible fire source.

00:14:40.022 --> 00:14:41.662
<v Grzegorz Krajewski>We don't have any limitations.

00:14:42.272 --> 00:14:43.621
<v Grzegorz Krajewski>So we can make.

00:14:43.687 --> 00:14:44.587
<v Grzegorz Krajewski>performance test.

00:14:44.827 --> 00:14:47.618
<v Grzegorz Krajewski>Of fire ventilation from the smallest fires to the biggest fires.

00:14:48.155 --> 00:14:53.706
<v Wojciech Wegrzynski>Oh, I wouldn't be so open the mode, like a limited, Because, I mean, there's a certain point.

00:14:53.946 --> 00:14:55.416
<v Wojciech Wegrzynski>which is the facility will be destroyed.

00:14:55.836 --> 00:14:58.424
<v Wojciech Wegrzynski>And actually we've, we, We have thought about that.

00:14:58.424 --> 00:15:04.081
<v Wojciech Wegrzynski>and it's, built from Easily fixable materials, almost disposable material.

00:15:04.081 --> 00:15:07.471
<v Wojciech Wegrzynski>So if we damage it, it's very, very easy to fix it.

00:15:08.251 --> 00:15:14.644
<v Wojciech Wegrzynski>There's the key fallen gravity Of the, of the facility, , but we are using propane burners with, uh, Heat release rate.

00:15:14.644 --> 00:15:16.625
<v Wojciech Wegrzynski>We, we do steer that's true.

00:15:17.105 --> 00:15:19.625
<v Wojciech Wegrzynski>Mass flow inlet of propane into the burner.

00:15:19.965 --> 00:15:23.259
<v Wojciech Wegrzynski>We Put multiple burners in the facility.

00:15:23.259 --> 00:15:27.609
<v Wojciech Wegrzynski>So we also influence somehow the kit release rate per unit area.

00:15:28.208 --> 00:15:36.009
<v Wojciech Wegrzynski>And, uh, because of that, we really have almost unlimited possibilities to, to test any fires and it's all computer controlled.

00:15:36.009 --> 00:15:36.158
<v Wojciech Wegrzynski>Right.

00:15:36.489 --> 00:15:36.729
<v Grzegorz Krajewski>Yeah,

00:15:36.759 --> 00:15:36.908
<v Wojciech Wegrzynski>We

00:15:37.178 --> 00:15:38.109
<v Grzegorz Krajewski>We can define any.

00:15:38.168 --> 00:15:42.578
<v Grzegorz Krajewski>And a fire curve, which we want so-so the fire heat release rate can change in time.

00:15:43.445 --> 00:15:44.615
<v Grzegorz Krajewski>As we, as we define it.

00:15:44.615 --> 00:15:45.034
<v Grzegorz Krajewski>So.

00:15:45.034 --> 00:15:47.318
<v Grzegorz Krajewski>and, At that moment, we have got four burners.

00:15:47.708 --> 00:15:49.538
<v Grzegorz Krajewski>So we can even make fire.

00:15:49.538 --> 00:15:51.668
<v Grzegorz Krajewski>to up to two megawatts, three megawatts.

00:15:51.938 --> 00:15:52.328
<v Grzegorz Krajewski>We.

00:15:52.538 --> 00:15:53.769
<v Wojciech Wegrzynski>I think three megawatts.

00:15:53.769 --> 00:15:56.198
<v Wojciech Wegrzynski>is even more than ventilation controlled for, for the compartments.

00:15:56.889 --> 00:15:58.099
<v Grzegorz Krajewski>but it will destroy the corridor.

00:15:58.989 --> 00:16:00.489
<v Wojciech Wegrzynski>I'm a little price to pay for knowledge.

00:16:01.778 --> 00:16:03.068
<v Wojciech Wegrzynski>this is fire source.

00:16:03.099 --> 00:16:03.369
<v Wojciech Wegrzynski>Okay.

00:16:03.399 --> 00:16:04.359
<v Wojciech Wegrzynski>That's a, that's a.

00:16:04.534 --> 00:16:10.085
<v Wojciech Wegrzynski>important aspect now smoke control systems, because I mean, you can build a building.

00:16:10.085 --> 00:16:13.552
<v Wojciech Wegrzynski>A corridor is not difficult or impressive on its own.

00:16:13.971 --> 00:16:23.511
<v Wojciech Wegrzynski>I think I would say the 20% of the struggle with the project was with building the And the rest was waste with the smoke control system suit.

00:16:23.511 --> 00:16:27.418
<v Wojciech Wegrzynski>So we equipped it with almost anything you can find on the market.

00:16:27.418 --> 00:16:32.971
<v Wojciech Wegrzynski>Like it Entangled Why ducks and of different smoke control?

00:16:35.025 --> 00:16:36.645
<v Grzegorz Krajewski>our only walls and sitting on the floor.

00:16:36.686 --> 00:16:39.842
<v Grzegorz Krajewski>. but the whole magic of the project was the, equipment.

00:16:39.873 --> 00:16:40.113
<v Grzegorz Krajewski>Yes.

00:16:40.113 --> 00:16:40.802
<v Grzegorz Krajewski>So we.

00:16:41.462 --> 00:16:44.322
<v Grzegorz Krajewski>looked, what kind of systems we have tested before.

00:16:44.373 --> 00:16:46.893
<v Grzegorz Krajewski>Uh, on that facility, I think we can perform.

00:16:47.673 --> 00:16:50.133
<v Grzegorz Krajewski>any test which we can imagine on a market.

00:16:50.133 --> 00:16:50.493
<v Grzegorz Krajewski>Yes.

00:16:50.493 --> 00:16:53.072
<v Grzegorz Krajewski>So for example, transversal ventilation system.

00:16:53.403 --> 00:16:57.192
<v Grzegorz Krajewski>Semi transversal ventilation system, long continuous ventilation system.

00:16:57.243 --> 00:16:59.399
<v Grzegorz Krajewski>we can, additionally, we can.

00:16:59.600 --> 00:17:05.779
<v Grzegorz Krajewski>Change the way, how we supply or exhaust the air from the corridor, it can be natural.

00:17:06.440 --> 00:17:06.950
<v Grzegorz Krajewski>supply.

00:17:08.029 --> 00:17:08.190
<v Grzegorz Krajewski>So.

00:17:08.960 --> 00:17:12.690
<v Grzegorz Krajewski>There are unlimited possibilities, which we can make on that facility.

00:17:13.519 --> 00:17:17.299
<v Wojciech Wegrzynski>And that there was a point too, to have ability to retest.

00:17:17.359 --> 00:17:19.069
<v Wojciech Wegrzynski>Uh, whatever solutions are used in the world.

00:17:19.205 --> 00:17:22.865
<v Wojciech Wegrzynski>And, It's obviously all computer controlled, just like the burner.

00:17:22.895 --> 00:17:23.105
<v Wojciech Wegrzynski>So.

00:17:23.375 --> 00:17:24.753
<v Wojciech Wegrzynski>With the click of a mouse, you can.

00:17:24.792 --> 00:17:29.143
<v Wojciech Wegrzynski>Turn the longitudinal system into transversal system and change the capacities and stuff like that.

00:17:29.623 --> 00:17:31.623
<v Grzegorz Krajewski>And this is the second advantage of that.

00:17:31.657 --> 00:17:31.920
<v Grzegorz Krajewski>project.

00:17:32.630 --> 00:17:34.730
<v Grzegorz Krajewski>Is that, that we can control everything.

00:17:35.329 --> 00:17:38.210
<v Grzegorz Krajewski>And everything is registered only in one file.

00:17:38.509 --> 00:17:39.740
<v Grzegorz Krajewski>So it's synchronized.

00:17:39.769 --> 00:17:42.462
<v Grzegorz Krajewski>So you can see the temperatures.

00:17:42.885 --> 00:17:47.205
<v Grzegorz Krajewski>and the level on the edge of the ventilators while working, we did numbers are open.

00:17:47.506 --> 00:17:50.625
<v Grzegorz Krajewski>What was the gas flow in on the regulators?

00:17:50.625 --> 00:17:50.955
<v Grzegorz Krajewski>So we have.

00:17:50.986 --> 00:17:53.772
<v Grzegorz Krajewski>I've got everything in one file Synchronized.

00:17:54.103 --> 00:17:55.633
<v Grzegorz Krajewski>So it's very easy to.

00:17:55.702 --> 00:17:58.732
<v Grzegorz Krajewski>repeat every test with the same,  input parameters.

00:17:59.373 --> 00:18:01.133
<v Wojciech Wegrzynski>So I hope in your head to your building.

00:18:01.885 --> 00:18:06.026
<v Wojciech Wegrzynski>Image of this magnificent facility, probably the image you build is more beautiful than that.

00:18:06.236 --> 00:18:07.026
<v Wojciech Wegrzynski>Facility itself.

00:18:07.826 --> 00:18:08.306
<v Wojciech Wegrzynski>It is.

00:18:08.695 --> 00:18:11.635
<v Wojciech Wegrzynski>It is really impressive on what can be done in here.

00:18:11.965 --> 00:18:16.135
<v Wojciech Wegrzynski>And now in important broad custom message to any one of you listening.

00:18:16.165 --> 00:18:20.276
<v Wojciech Wegrzynski>If, if you are intrigued with what we have.

00:18:20.756 --> 00:18:27.715
<v Wojciech Wegrzynski>If you like what we have, and you have an idea on how to use it to enhance your own research, like.

00:18:28.105 --> 00:18:29.306
<v Wojciech Wegrzynski>Please, please just contact us.

00:18:29.306 --> 00:18:31.375
<v Wojciech Wegrzynski>I mean, we're, , We are fueled by collaboration.

00:18:31.425 --> 00:18:33.465
<v Wojciech Wegrzynski>We believe in collaborative nature of science.

00:18:33.885 --> 00:18:35.566
<v Wojciech Wegrzynski>I don't like individualism in science.

00:18:35.596 --> 00:18:36.796
<v Wojciech Wegrzynski>I like collaborations.

00:18:36.915 --> 00:18:40.786
<v Wojciech Wegrzynski>So if you have a better idea on how to use it than us, Please let us know.

00:18:40.996 --> 00:18:42.915
<v Wojciech Wegrzynski>and we'll, we'll try to do it.

00:18:42.976 --> 00:18:44.476
<v Wojciech Wegrzynski>The beauty of the facility is that.

00:18:44.806 --> 00:18:49.786
<v Wojciech Wegrzynski>it took three years to build, but now to set up an experiment, it's like few hours in one day.

00:18:50.296 --> 00:18:52.086
<v Wojciech Wegrzynski>Literally in the first day of burning.

00:18:52.635 --> 00:18:53.296
<v Wojciech Wegrzynski>It was amazing.

00:18:53.296 --> 00:18:56.185
<v Wojciech Wegrzynski>We have done how many, these are three, four tests.

00:18:58.036 --> 00:18:58.756
<v Grzegorz Krajewski>Four tests.

00:18:58.786 --> 00:18:58.885
<v Grzegorz Krajewski>Yes.

00:18:59.086 --> 00:19:02.256
<v Grzegorz Krajewski>We bought, we, we have been changing many times the ventilation system.

00:19:02.256 --> 00:19:02.675
<v Grzegorz Krajewski>So.

00:19:03.425 --> 00:19:05.185
<v Grzegorz Krajewski>During Quantus you are making 20 tests.

00:19:05.705 --> 00:19:07.685
<v Wojciech Wegrzynski>So this is one day of testing.

00:19:07.685 --> 00:19:08.060
<v Wojciech Wegrzynski>I think.

00:19:08.060 --> 00:19:10.029
<v Wojciech Wegrzynski>I think it's a first statement.

00:19:10.029 --> 00:19:17.806
<v Wojciech Wegrzynski>I think we've generated more useful results for validating CFD than I've seen in the literature on this of the subject.

00:19:18.165 --> 00:19:19.665
<v Wojciech Wegrzynski>Through my entire career.

00:19:19.726 --> 00:19:21.016
<v Wojciech Wegrzynski>And there was just one day of test.

00:19:21.016 --> 00:19:21.286
<v Wojciech Wegrzynski>So.

00:19:21.796 --> 00:19:24.915
<v Wojciech Wegrzynski>The possibilities Are endless and you're all invited to, to participate.

00:19:24.915 --> 00:19:27.076
<v Wojciech Wegrzynski>We want this to be a living facility.

00:19:27.076 --> 00:19:28.046
<v Wojciech Wegrzynski>We want this to be yielding.

00:19:28.905 --> 00:19:31.063
<v Wojciech Wegrzynski>Useful results for, for science, for everyone.

00:19:31.386 --> 00:19:32.616
<v Grzegorz Krajewski>Now we have the.

00:19:32.616 --> 00:19:33.396
<v Grzegorz Krajewski>boom, the base.

00:19:33.426 --> 00:19:33.666
<v Grzegorz Krajewski>Yes.

00:19:33.666 --> 00:19:36.027
<v Grzegorz Krajewski>So we can extend it in  every possible way.

00:19:36.057 --> 00:19:37.586
<v Grzegorz Krajewski>So any ideas.

00:19:38.487 --> 00:19:40.186
<v Grzegorz Krajewski>Just to feel welcome to a contact with.

00:19:40.326 --> 00:19:40.777
<v Grzegorz Krajewski>We've asked.

00:19:40.777 --> 00:19:41.876
<v Grzegorz Krajewski>so we will try to

00:19:43.701 --> 00:19:46.800
<v Wojciech Wegrzynski>And now,  As I mentioned, the experimental facilities is just one piece of the puzzle.

00:19:47.490 --> 00:19:51.101
<v Wojciech Wegrzynski>The second piece is the digital twin, which is a fancy way to call.

00:19:51.570 --> 00:19:53.891
<v Wojciech Wegrzynski>Uh, let's see if this simulations for the facility.

00:19:54.310 --> 00:19:58.250
<v Wojciech Wegrzynski>And here, we approached the project the same way as the corridor.

00:19:58.671 --> 00:20:00.371
<v Wojciech Wegrzynski>We wanted to be modular.

00:20:01.131 --> 00:20:02.931
<v Wojciech Wegrzynski>We wanted to be a parametric.

00:20:02.931 --> 00:20:04.161
<v Wojciech Wegrzynski>We wanted to be.

00:20:04.580 --> 00:20:07.054
<v Wojciech Wegrzynski>Like, able , to verify whatever we need.

00:20:07.354 --> 00:20:07.923
<v Wojciech Wegrzynski>And.

00:20:08.080 --> 00:20:09.911
<v Wojciech Wegrzynski>Anyone who's working with CV models.

00:20:10.000 --> 00:20:19.000
<v Wojciech Wegrzynski>You probably realize how painful it is to set see if the Moodle and it's even more painful to change something like you want to move your extraction point by one meter.

00:20:19.421 --> 00:20:24.161
<v Wojciech Wegrzynski>To your left and then eventually it gets into middle of two meshes of LDS.

00:20:24.161 --> 00:20:29.320
<v Wojciech Wegrzynski>So you have to split There's so many annoying things that can happen when you change.

00:20:29.320 --> 00:20:30.971
<v Wojciech Wegrzynski>a parameter in your CFD.

00:20:31.421 --> 00:20:33.181
<v Wojciech Wegrzynski>And that will, because we are talking about.

00:20:33.413 --> 00:20:35.784
<v Wojciech Wegrzynski>Literally hundreds of barometers, literally.

00:20:35.894 --> 00:20:38.354
<v Wojciech Wegrzynski>Thousands of possible scenarios to be tested.

00:20:39.344 --> 00:20:40.953
<v Wojciech Wegrzynski>There's no way you can program that by hand.

00:20:41.166 --> 00:20:42.547
<v Wojciech Wegrzynski>It would be too much.

00:20:42.842 --> 00:20:44.342
<v Wojciech Wegrzynski>So we've approached this in a different way.

00:20:44.791 --> 00:20:48.461
<v Wojciech Wegrzynski>Some of those similar to, to how we did our top acquisition that I've shown in the past.

00:20:48.791 --> 00:20:52.711
<v Wojciech Wegrzynski>We have taken, snippets off of the us code to describe parts of the model.

00:20:53.471 --> 00:20:54.912
<v Wojciech Wegrzynski>Like I have a snippet of the code that.

00:20:54.912 --> 00:20:57.112
<v Wojciech Wegrzynski>describes the corridor and the compartments.

00:20:57.306 --> 00:21:02.226
<v Wojciech Wegrzynski>There's a snippet of the code that describes the ventilation systems, fire devices using the cord.

00:21:02.226 --> 00:21:05.316
<v Wojciech Wegrzynski>And we're like, every, everything is split into separate snippet.

00:21:05.355 --> 00:21:05.836
<v Wojciech Wegrzynski>Files.

00:21:05.836 --> 00:21:08.925
<v Wojciech Wegrzynski>And then I have, we have a parametric scripts.

00:21:08.955 --> 00:21:15.246
<v Wojciech Wegrzynski>that whenever they are fueled with the list of variables to be investigated, They take the the snippets.

00:21:15.306 --> 00:21:16.096
<v Wojciech Wegrzynski>That are needed.

00:21:16.326 --> 00:21:22.395
<v Wojciech Wegrzynski>To, to build this particular case file and they just With the values of That we have defined too.

00:21:23.195 --> 00:21:23.976
<v Wojciech Wegrzynski>It's a model.

00:21:24.125 --> 00:21:24.195
<v Wojciech Wegrzynski>I.

00:21:24.395 --> 00:21:27.955
<v Wojciech Wegrzynski>I mean after two, after it works, I.

00:21:28.086 --> 00:21:28.925
<v Wojciech Wegrzynski>Just give it lists.

00:21:28.955 --> 00:21:31.955
<v Wojciech Wegrzynski>Just, I want to have Like FDS simulations of.

00:21:32.105 --> 00:21:34.326
<v Wojciech Wegrzynski>Uh, firing room number Number two number three.

00:21:34.655 --> 00:21:36.355
<v Wojciech Wegrzynski>One megawatt two megawatt, three megawatts.

00:21:37.056 --> 00:21:37.925
<v Wojciech Wegrzynski>I want a smoke.

00:21:38.316 --> 00:21:38.826
<v Wojciech Wegrzynski>Extraction.

00:21:39.486 --> 00:21:40.986
<v Wojciech Wegrzynski>Point three points, five points.

00:21:41.526 --> 00:21:44.455
<v Wojciech Wegrzynski>We had the capacity Oh, 2, 5, 10 meters per second.

00:21:44.736 --> 00:21:45.486
<v Wojciech Wegrzynski>Let's hear.

00:21:46.026 --> 00:21:49.955
<v Wojciech Wegrzynski>And then I just present her and It's me hundreds or thousands of 50.

00:21:50.105 --> 00:21:50.955
<v Wojciech Wegrzynski>Yes files to describe.

00:21:51.215 --> 00:21:52.155
<v Wojciech Wegrzynski>The recombination of these variables.

00:21:52.630 --> 00:21:55.900
<v Wojciech Wegrzynski>Then it automatically sends it Our HPC cluster.

00:21:56.380 --> 00:21:56.799
<v Wojciech Wegrzynski>And they.

00:21:57.579 --> 00:21:58.210
<v Wojciech Wegrzynski>And then.

00:21:58.509 --> 00:21:59.920
<v Wojciech Wegrzynski>a month later we come back.

00:22:00.279 --> 00:22:01.329
<v Wojciech Wegrzynski>We pick up the results.

00:22:01.359 --> 00:22:01.930
<v Wojciech Wegrzynski>there's there are.

00:22:01.930 --> 00:22:02.930
<v Wojciech Wegrzynski>Our scripts that automatically.

00:22:03.130 --> 00:22:04.150
<v Wojciech Wegrzynski>The process that.

00:22:04.720 --> 00:22:06.099
<v Wojciech Wegrzynski>and w we're we're done.

00:22:06.579 --> 00:22:09.099
<v Wojciech Wegrzynski>I think it's super powerful and especially.

00:22:09.250 --> 00:22:12.130
<v Wojciech Wegrzynski>That we consider these two things.

00:22:12.940 --> 00:22:13.430
<v Wojciech Wegrzynski>As.

00:22:14.019 --> 00:22:16.150
<v Wojciech Wegrzynski>Two parts of one exact thing.

00:22:16.210 --> 00:22:16.509
<v Wojciech Wegrzynski>Like.

00:22:16.960 --> 00:22:18.630
<v Wojciech Wegrzynski>You don't see everything from the Experis.

00:22:19.359 --> 00:22:22.000
<v Wojciech Wegrzynski>Measurements, but if you have validated CFD that.

00:22:22.029 --> 00:22:22.750
<v Wojciech Wegrzynski>You trust?

00:22:23.380 --> 00:22:24.700
<v Wojciech Wegrzynski>You can make an experiment.

00:22:25.359 --> 00:22:26.329
<v Wojciech Wegrzynski>And then use the CFD.

00:22:27.160 --> 00:22:27.829
<v Wojciech Wegrzynski>To understand more

00:22:28.369 --> 00:22:32.289
<v Grzegorz Krajewski>especially what you did We designed that fascinating.

00:22:32.660 --> 00:22:33.259
<v Grzegorz Krajewski>And before.

00:22:33.289 --> 00:22:35.059
<v Grzegorz Krajewski>We build it and.

00:22:35.288 --> 00:22:35.618
<v Grzegorz Krajewski>Heads.

00:22:35.679 --> 00:22:37.648
<v Grzegorz Krajewski>The idea how it is going to work.

00:22:38.229 --> 00:22:40.749
<v Grzegorz Krajewski>Eh, we did plenty of CFD calculations.

00:22:41.439 --> 00:22:43.239
<v Grzegorz Krajewski>At the beginning, it was about 700.

00:22:43.538 --> 00:22:44.449
<v Grzegorz Krajewski>CFD calculations.

00:22:45.278 --> 00:22:48.249
<v Grzegorz Krajewski>To predict what is going to happen during the tests?

00:22:49.148 --> 00:22:52.848
<v Grzegorz Krajewski>And it was our input data to design that facility.

00:22:53.769 --> 00:22:56.019
<v Grzegorz Krajewski>.

00:22:53.769 --> 00:22:59.151
<v Grzegorz Krajewski>and to find out the experimental part Of the topic.

00:22:59.800 --> 00:22:59.921
<v Wojciech Wegrzynski>Yeah.

00:23:00.250 --> 00:23:02.171
<v Wojciech Wegrzynski>so it's really both things fuel.

00:23:02.500 --> 00:23:03.221
<v Wojciech Wegrzynski>on each other.

00:23:03.550 --> 00:23:05.681
<v Wojciech Wegrzynski>Both things are very interconnected.

00:23:05.681 --> 00:23:10.030
<v Wojciech Wegrzynski>and definitely experiments are the number one thing we want to do.

00:23:10.030 --> 00:23:15.280
<v Wojciech Wegrzynski>We want to find experimental proof for various smoke control and performance in corridors.

00:23:15.280 --> 00:23:15.998
<v Wojciech Wegrzynski>We want to have.

00:23:15.998 --> 00:23:18.635
<v Wojciech Wegrzynski>experimental proof on what really happens in the corridors.

00:23:18.965 --> 00:23:26.435
<v Wojciech Wegrzynski>That's the number one But thanks to digital twin, we can easily enhance that knowledge with with much more data points.

00:23:27.066 --> 00:23:27.365
<v Wojciech Wegrzynski>That.

00:23:27.365 --> 00:23:29.195
<v Wojciech Wegrzynski>we would not be able to find otherwise.

00:23:29.465 --> 00:23:36.388
<v Grzegorz Krajewski>And we knew how to design it and now we can validate it, having the final data from, from the experiment.

00:23:36.689 --> 00:23:37.588
<v Wojciech Wegrzynski>Oh Yeah, that's that's cool.

00:23:37.648 --> 00:23:38.338
<v Wojciech Wegrzynski>Let's talk about validation.

00:23:39.088 --> 00:23:39.628
<v Wojciech Wegrzynski>Good idea.

00:23:40.108 --> 00:23:43.739
<v Wojciech Wegrzynski>We have performance as mentioned so far, 13 experiments.

00:23:43.739 --> 00:23:43.769
<v Wojciech Wegrzynski>I

00:23:44.638 --> 00:23:47.398
<v Grzegorz Krajewski>14 experiments, but with many variables, Between.

00:23:47.489 --> 00:23:49.038
<v Grzegorz Krajewski>in each experiment,

00:23:49.148 --> 00:23:49.288
<v Wojciech Wegrzynski>Yes.

00:23:49.828 --> 00:23:51.358
<v Wojciech Wegrzynski>Just to take us to an experiment like.

00:23:52.108 --> 00:23:53.999
<v Wojciech Wegrzynski>Let let let's talk about the ones with variable.

00:23:54.028 --> 00:23:54.659
<v Wojciech Wegrzynski>He truly straights.

00:23:54.689 --> 00:23:55.679
<v Wojciech Wegrzynski>What are we changing?

00:23:55.679 --> 00:23:56.459
<v Wojciech Wegrzynski>How do we do that?

00:23:56.576 --> 00:23:57.056
<v Grzegorz Krajewski>at the beginning.

00:23:57.056 --> 00:23:57.355
<v Grzegorz Krajewski>increment.

00:23:57.536 --> 00:23:58.586
<v Grzegorz Krajewski>very simple test to.

00:23:58.615 --> 00:24:05.276
<v Grzegorz Krajewski>just a constant It treats rates 100 kilowatts per one hour, just to check what is going.

00:24:05.546 --> 00:24:05.986
<v Grzegorz Krajewski>on with our.

00:24:06.203 --> 00:24:06.788
<v Grzegorz Krajewski>a facility.

00:24:06.818 --> 00:24:09.145
<v Grzegorz Krajewski>is Because we are not able to predict.

00:24:09.185 --> 00:24:12.486
<v Grzegorz Krajewski>If it We'll stay alive after one test.

00:24:12.486 --> 00:24:12.935
<v Grzegorz Krajewski>So.

00:24:13.531 --> 00:24:14.115
<v Grzegorz Krajewski>Until now?

00:24:14.115 --> 00:24:14.555
<v Grzegorz Krajewski>yes.

00:24:15.135 --> 00:24:21.826
<v Grzegorz Krajewski>So first we started from the steady state fires lasting one hour, half an hour until we have.

00:24:21.826 --> 00:24:22.163
<v Grzegorz Krajewski>got.

00:24:22.182 --> 00:24:23.521
<v Grzegorz Krajewski>steady state conditions.

00:24:23.715 --> 00:24:26.925
<v Grzegorz Krajewski>And later we started to change.

00:24:26.955 --> 00:24:28.875
<v Grzegorz Krajewski>He trees red during the tests.

00:24:28.935 --> 00:24:30.705
<v Grzegorz Krajewski>after every five minutes.

00:24:30.855 --> 00:24:32.816
<v Grzegorz Krajewski>we were increasing the Patrice rate.

00:24:33.226 --> 00:24:34.016
<v Grzegorz Krajewski>starting from 50.

00:24:34.695 --> 00:24:36.516
<v Grzegorz Krajewski>Kilowatts up to 500 kilowatts.

00:24:37.246 --> 00:24:40.276
<v Grzegorz Krajewski>and then decrease down, just looking what is happening with.

00:24:40.276 --> 00:24:40.915
<v Grzegorz Krajewski>The temperatures.

00:24:41.176 --> 00:24:42.189
<v Grzegorz Krajewski>along the corridor.

00:24:42.368 --> 00:24:42.489
<v Wojciech Wegrzynski>Yeah.

00:24:42.638 --> 00:24:44.318
<v Wojciech Wegrzynski>It's on the plus it looks like.

00:24:44.378 --> 00:24:47.583
<v Wojciech Wegrzynski>Uh, pyramid with the steps that, it's gross.

00:24:47.853 --> 00:24:51.353
<v Wojciech Wegrzynski>then stays stable for like five minutes and grows again and again, and

00:24:51.423 --> 00:24:51.722
<v Grzegorz Krajewski>again.

00:24:52.083 --> 00:24:52.262
<v Grzegorz Krajewski>.

00:24:52.083 --> 00:24:52.472
<v Grzegorz Krajewski>Wojciech Wegrzynski: But a

00:24:52.593 --> 00:24:53.462
<v Wojciech Wegrzynski>yeah, you control.

00:24:53.883 --> 00:24:54.303
<v Wojciech Wegrzynski>Yeah.

00:24:54.452 --> 00:24:58.532
<v Wojciech Wegrzynski>but it's a really great too, because it generates you plenty of data to validate.

00:24:59.403 --> 00:25:01.653
<v Wojciech Wegrzynski>And obviously for this experiments, we have performed.

00:25:02.252 --> 00:25:02.972
<v Wojciech Wegrzynski>If deal with MDs.

00:25:03.512 --> 00:25:06.782
<v Wojciech Wegrzynski>Taking just the basic settings of the model, like really.

00:25:06.786 --> 00:25:08.425
<v Wojciech Wegrzynski>Not playing with anything.

00:25:08.855 --> 00:25:12.395
<v Wojciech Wegrzynski>Not touching any more advanced settings of the solver.

00:25:12.663 --> 00:25:17.613
<v Wojciech Wegrzynski>For the smaller fires, we got almost ideal match between the simulations and experiments.

00:25:17.613 --> 00:25:18.012
<v Grzegorz Krajewski>experiments.

00:25:18.722 --> 00:25:22.445
<v Wojciech Wegrzynski>For the more complicated cases, especially this style Grow the fires.

00:25:22.445 --> 00:25:24.935
<v Wojciech Wegrzynski>we've have found some discrepancies.

00:25:24.965 --> 00:25:26.736
<v Wojciech Wegrzynski>The temperatures in the experiments.

00:25:27.306 --> 00:25:29.405
<v Wojciech Wegrzynski>Are approximately 50 degrees.

00:25:29.556 --> 00:25:30.435
<v Wojciech Wegrzynski>Higher than the CFD.

00:25:31.355 --> 00:25:33.576
<v Wojciech Wegrzynski>Which I mean it's okay.

00:25:33.605 --> 00:25:36.276
<v Wojciech Wegrzynski>Ish for a first shot, but we're, we're not very happy with it.

00:25:36.306 --> 00:25:36.875
<v Wojciech Wegrzynski>. we hope to him.

00:25:37.145 --> 00:25:42.006
<v Wojciech Wegrzynski>prove it, but there's like, we already have good ideas on where to look for, for solutions to that.

00:25:42.336 --> 00:25:45.355
<v Wojciech Wegrzynski>So overall, over the cause of this 13 simulations.

00:25:45.786 --> 00:25:48.361
<v Wojciech Wegrzynski>We already have something like if they did save the model, Yeah.

00:25:48.421 --> 00:25:48.631
<v Grzegorz Krajewski>but

00:25:48.780 --> 00:25:50.480
<v Wojciech Wegrzynski>We have a lot of doubts yes.

00:25:50.550 --> 00:25:51.310
<v Wojciech Wegrzynski>, especially when you are

00:25:51.391 --> 00:25:52.830
<v Grzegorz Krajewski>making a full-scale experiement.

00:25:52.973 --> 00:25:53.213
<v Grzegorz Krajewski>.

00:25:52.973 --> 00:25:53.213
<v Grzegorz Krajewski>There

00:25:53.243 --> 00:25:54.683
<v Wojciech Wegrzynski>are many, many questions.

00:25:54.773 --> 00:25:57.483
<v Wojciech Wegrzynski>If your, history's rate of fire is.

00:25:57.528 --> 00:25:58.038
<v Wojciech Wegrzynski>Exactly.

00:25:58.097 --> 00:26:00.038
<v Wojciech Wegrzynski>That's what you predict at the beginning.

00:26:00.107 --> 00:26:00.377
<v Grzegorz Krajewski>Cause

00:26:00.407 --> 00:26:03.137
<v Wojciech Wegrzynski>That's why we are going to make another test in the wrong corner.

00:26:03.587 --> 00:26:03.738
<v Grzegorz Krajewski>To

00:26:04.127 --> 00:26:06.238
<v Wojciech Wegrzynski>verify our This rate of the burner.

00:26:06.978 --> 00:26:07.738
<v Wojciech Wegrzynski>For the career values.

00:26:08.417 --> 00:26:11.468
<v Wojciech Wegrzynski>Yeah, we, we used to prop in burners with mass flow controllers.

00:26:12.208 --> 00:26:14.877
<v Wojciech Wegrzynski>That lowest to set any value of propane flow.

00:26:15.327 --> 00:26:16.107
<v Wojciech Wegrzynski>Into the burner.

00:26:16.107 --> 00:26:22.413
<v Wojciech Wegrzynski>And with previous experience in open air measurements of these burners, we were quite happy with.

00:26:22.933 --> 00:26:30.777
<v Wojciech Wegrzynski>How they work, but now as they are in the confined space of the corridor, there are some doubts how this can influence the heat release rate, Actually, Okay.

00:26:30.777 --> 00:26:30.856
<v Wojciech Wegrzynski>And.

00:26:31.017 --> 00:26:31.227
<v Wojciech Wegrzynski>And.

00:26:31.227 --> 00:26:33.416
<v Wojciech Wegrzynski>now Let's move into the future.

00:26:33.416 --> 00:26:35.007
<v Wojciech Wegrzynski>How do we see the use of this facility?

00:26:35.037 --> 00:26:37.767
<v Wojciech Wegrzynski>Like we finished the stage one building starting.

00:26:38.576 --> 00:26:39.596
<v Wojciech Wegrzynski>We're in the.

00:26:40.467 --> 00:26:42.896
<v Wojciech Wegrzynski>Final phases of validation of the CFDs.

00:26:43.166 --> 00:26:44.307
<v Wojciech Wegrzynski>the facility is up and running.

00:26:44.366 --> 00:26:46.797
<v Wojciech Wegrzynski>The experiments are fairly easy to set up.

00:26:46.916 --> 00:26:47.636
<v Wojciech Wegrzynski>Of course there are not.

00:26:47.636 --> 00:26:50.997
<v Wojciech Wegrzynski>without with, without the problems, but everything's manageable.

00:26:51.027 --> 00:26:51.957
<v Wojciech Wegrzynski>Everything's working.

00:26:52.557 --> 00:26:54.257
<v Wojciech Wegrzynski>As we expected it to work.

00:26:55.076 --> 00:26:57.146
<v Wojciech Wegrzynski>Now, where are we going with Jewish?

00:26:57.507 --> 00:27:01.767
<v Grzegorz Krajewski>At this moment, I think we are planning to extend a lot amount of term of couples.

00:27:01.826 --> 00:27:07.047
<v Grzegorz Krajewski>to have a more dense greet , of points when we measured the temperature.

00:27:07.559 --> 00:27:10.440
<v Grzegorz Krajewski>We are going to add additional thermocouples trees.

00:27:10.440 --> 00:27:11.549
<v Grzegorz Krajewski>We are going to add.

00:27:12.269 --> 00:27:13.740
<v Grzegorz Krajewski>At the floor and in the ceiling.

00:27:13.890 --> 00:27:17.049
<v Grzegorz Krajewski>And At the end of September, we will have, the.

00:27:17.140 --> 00:27:21.180
<v Grzegorz Krajewski>possibility to measure the intensity of radiation.

00:27:21.470 --> 00:27:22.549
<v Wojciech Wegrzynski>Yeah, I'm also looking into.

00:27:22.579 --> 00:27:24.410
<v Wojciech Wegrzynski>putting oxygen and measurements into the corridor.

00:27:24.769 --> 00:27:26.720
<v Wojciech Wegrzynski>to have a better comparison with the CFD.

00:27:26.750 --> 00:27:31.460
<v Wojciech Wegrzynski>And we've not mentioned that, but we also are measuring the velocities in the smoke layer.

00:27:31.819 --> 00:27:44.787
<v Wojciech Wegrzynski>In the, in the ceiling jet, which also will be To compare the data we have with, uh, with the CFD, but not only with, with also with sewn models, with outbursts correlations, with the corridor ceiling jet models.

00:27:45.257 --> 00:27:47.626
<v Wojciech Wegrzynski>Opens quite a lot of possibilities there.

00:27:48.017 --> 00:27:49.993
<v Grzegorz Krajewski>And after we finished our plan of.

00:27:50.483 --> 00:27:53.136
<v Grzegorz Krajewski>making The combination of five ventilation.

00:27:53.166 --> 00:27:56.233
<v Grzegorz Krajewski>when we have got Heat and smoke in the middle  of corridor.

00:27:57.094 --> 00:28:04.534
<v Grzegorz Krajewski>We are just relocated the burner And we will start the , real tests of five ventilation system.

00:28:04.534 --> 00:28:07.327
<v Grzegorz Krajewski>When we have got the fire Compartment.

00:28:07.653 --> 00:28:08.064
<v Wojciech Wegrzynski>including.

00:28:08.223 --> 00:28:11.163
<v Wojciech Wegrzynski>Uh, shutting the doors at different posts, points of experiment, opening them.

00:28:11.824 --> 00:28:16.413
<v Wojciech Wegrzynski>Opening the windows in the compartments, changing the size of the Many many variables to play.

00:28:16.443 --> 00:28:16.773
<v Wojciech Wegrzynski>Right.

00:28:16.894 --> 00:28:17.943
<v Grzegorz Krajewski>Exactly like that.

00:28:18.064 --> 00:28:19.564
<v Grzegorz Krajewski>and probably.

00:28:19.734 --> 00:28:23.124
<v Grzegorz Krajewski>In the end of this year, we'll have sprinkler systems.

00:28:23.124 --> 00:28:31.213
<v Grzegorz Krajewski>So we'll try to make some preliminary tests of how a smoke layer and how temperature field is changing Quinn.

00:28:31.513 --> 00:28:33.493
<v Grzegorz Krajewski>Sprinkler system is running.

00:28:34.034 --> 00:28:34.433
<v Wojciech Wegrzynski>We also have

00:28:35.453 --> 00:28:35.970
<v Grzegorz Krajewski>Walter Meese 10

00:28:36.900 --> 00:28:37.170
<v Wojciech Wegrzynski>Fantastic.

00:28:37.642 --> 00:28:38.210
<v Wojciech Wegrzynski>Fantastic.

00:28:38.210 --> 00:28:39.920
<v Wojciech Wegrzynski>I'm looking, I'm looking forward to that.

00:28:40.339 --> 00:28:42.554
<v Wojciech Wegrzynski>And, How do you see the facility in what?

00:28:42.584 --> 00:28:43.753
<v Wojciech Wegrzynski>One to three years.

00:28:43.753 --> 00:28:51.824
<v Wojciech Wegrzynski>Like well, we're, hopefully we won't burn That's like number one thing, but hopefully we can use for something good.

00:28:52.153 --> 00:28:54.463
<v Wojciech Wegrzynski>What was the craziest piece of research you would like to do on land?

00:28:54.890 --> 00:28:58.099
<v Grzegorz Krajewski>I think we will try to make a big fire as possible.

00:28:58.099 --> 00:28:58.369
<v Grzegorz Krajewski>Yes.

00:28:58.369 --> 00:29:01.920
<v Grzegorz Krajewski>Especially that we are making the commissioning tests Exactly.

00:29:02.119 --> 00:29:03.119
<v Grzegorz Krajewski>I don't know what is the limit?

00:29:03.980 --> 00:29:05.602
<v Grzegorz Krajewski>Of five ventilation system.

00:29:05.630 --> 00:29:08.180
<v Grzegorz Krajewski>to make the proof that it works properly.

00:29:08.309 --> 00:29:08.730
<v Wojciech Wegrzynski>Yeah.

00:29:08.910 --> 00:29:13.380
<v Grzegorz Krajewski>we combine everything together, a sprinkler system, Inflation system detection system.

00:29:13.740 --> 00:29:15.500
<v Grzegorz Krajewski>We will try to make the fire scenarios.

00:29:15.750 --> 00:29:18.299
<v Grzegorz Krajewski>As flexible as possible is because we are going to.

00:29:18.869 --> 00:29:23.599
<v Grzegorz Krajewski>Make some, detection system, which will decide which dam we did not post.

00:29:23.700 --> 00:29:24.700
<v Grzegorz Krajewski>It should be open, which samples.

00:29:25.230 --> 00:29:30.299
<v Grzegorz Krajewski>Dumpers should be So we are going to do way to some kind of an intelligence system.

00:29:30.960 --> 00:29:32.009
<v Wojciech Wegrzynski>I'm also looking forward.

00:29:32.060 --> 00:29:38.307
<v Wojciech Wegrzynski>To some more in middle next year when we will install the pressurization systems next to the corridor.

00:29:38.336 --> 00:29:43.616
<v Wojciech Wegrzynski>So we can check the influence on how a quick stream of air changes.

00:29:43.616 --> 00:29:43.707
<v Wojciech Wegrzynski>The.

00:29:44.336 --> 00:29:46.287
<v Wojciech Wegrzynski>Buoyancy of the smoke later in the corridor.

00:29:46.557 --> 00:29:48.477
<v Wojciech Wegrzynski>How do these systems work together?

00:29:48.477 --> 00:29:52.307
<v Wojciech Wegrzynski>I think there is so much to uncover there.

00:29:52.767 --> 00:29:56.366
<v Wojciech Wegrzynski>That can influence both the ways, how we design the smoke control but also.

00:29:56.366 --> 00:29:57.267
<v Wojciech Wegrzynski>the pressurization

00:29:57.507 --> 00:30:04.210
<v Grzegorz Krajewski>And the next problem, which we are going to to check is that because involved in, wind engineering.

00:30:04.210 --> 00:30:11.869
<v Grzegorz Krajewski>So, uh, As soon there are windows in rooms, there are , glass parts of the, of the facets, which can just break down.

00:30:12.109 --> 00:30:14.259
<v Grzegorz Krajewski>So we are going to check what will happen.

00:30:14.779 --> 00:30:18.359
<v Grzegorz Krajewski>If you have got some influence of the wind, which is outside of the corridor.

00:30:19.130 --> 00:30:21.859
<v Grzegorz Krajewski>And how it influence on the fire ventilation systems.

00:30:22.490 --> 00:30:22.880
<v Grzegorz Krajewski>So, but.

00:30:22.940 --> 00:30:24.230
<v Grzegorz Krajewski>it's the topic for next year?

00:30:24.230 --> 00:30:24.500
<v Grzegorz Krajewski>I think

00:30:24.529 --> 00:30:24.680
<v Wojciech Wegrzynski>so.

00:30:24.890 --> 00:30:27.799
<v Wojciech Wegrzynski>I think you've already seen some of that accidentally in the experiment.

00:30:27.829 --> 00:30:28.059
<v Wojciech Wegrzynski>Six.

00:30:28.519 --> 00:30:31.460
<v Wojciech Wegrzynski>where you had strong winds acting on your natural openings in the.

00:30:31.970 --> 00:30:34.519
<v Wojciech Wegrzynski>In the corridor And the whole smoke lady was fluctuating.

00:30:34.700 --> 00:30:35.869
<v Wojciech Wegrzynski>We have this crazy measurements.

00:30:36.200 --> 00:30:38.210
<v Grzegorz Krajewski>Yeah, we have got the big bumping of Temperature.

00:30:38.210 --> 00:30:38.809
<v Grzegorz Krajewski>So.

00:30:38.876 --> 00:30:40.086
<v Grzegorz Krajewski>do this test.

00:30:40.086 --> 00:30:40.508
<v Grzegorz Krajewski>It's not.

00:30:40.527 --> 00:30:42.656
<v Grzegorz Krajewski>easy to validate, but it happened.

00:30:42.656 --> 00:30:43.017
<v Grzegorz Krajewski>He has because.

00:30:43.136 --> 00:30:43.586
<v Wojciech Wegrzynski>I like it.

00:30:43.616 --> 00:30:52.586
<v Wojciech Wegrzynski>I actually like it because when you pulled the temperature over the FDS simulation, you see the average is matching that just in the real world.

00:30:52.586 --> 00:31:00.656
<v Wojciech Wegrzynski>cases, the temperatures were going up down 50 degrees when the wind was blowing on the facility and have It's just perfect uniform conditions.

00:31:01.076 --> 00:31:02.487
<v Wojciech Wegrzynski>It doesn't mean it's useless.

00:31:02.636 --> 00:31:04.136
<v Wojciech Wegrzynski>I think it's interesting.

00:31:04.136 --> 00:31:04.527
<v Wojciech Wegrzynski>And.

00:31:04.977 --> 00:31:12.386
<v Wojciech Wegrzynski>what you said taking wind into account when designing corridors wind-driven fires have been known for ages for decades that.

00:31:12.777 --> 00:31:13.416
<v Wojciech Wegrzynski>They are challenged.

00:31:13.743 --> 00:31:14.703
<v Wojciech Wegrzynski>Devastating.

00:31:14.703 --> 00:31:15.304
<v Wojciech Wegrzynski>They're deadly.

00:31:15.693 --> 00:31:16.743
<v Wojciech Wegrzynski>So absolutely.

00:31:16.743 --> 00:31:20.703
<v Wojciech Wegrzynski>That's a, that's a, something to And do you know Understanding.

00:31:21.183 --> 00:31:24.854
<v Wojciech Wegrzynski>To what extent wind actually influences the performance of mechanical smoke ventilation.

00:31:25.653 --> 00:31:26.374
<v Wojciech Wegrzynski>That's something.

00:31:26.433 --> 00:31:28.804
<v Wojciech Wegrzynski>I don't think we have a good answer yet.

00:31:28.946 --> 00:31:31.477
<v Grzegorz Krajewski>We don't have an answer but as you remember, we were making.

00:31:32.007 --> 00:31:35.926
<v Grzegorz Krajewski>A lot of commissioning testing, high-rise building where there was a facade with open windows.

00:31:36.386 --> 00:31:38.890
<v Grzegorz Krajewski>And if there was a wind outside , of the building.

00:31:39.001 --> 00:31:42.779
<v Grzegorz Krajewski>the five ventilation system didn't work exactly as it was designed.

00:31:42.839 --> 00:31:43.279
<v Grzegorz Krajewski>And E.

00:31:43.380 --> 00:31:44.759
<v Grzegorz Krajewski>as it was predicted by the.

00:31:44.789 --> 00:31:45.420
<v Grzegorz Krajewski>The designer.

00:31:45.839 --> 00:31:48.480
<v Grzegorz Krajewski>So that's what we would like to test in next year.

00:31:49.049 --> 00:31:51.480
<v Wojciech Wegrzynski>I think, you know, the coolest thing is that.

00:31:52.289 --> 00:31:53.430
<v Wojciech Wegrzynski>We have this.

00:31:53.480 --> 00:31:55.069
<v Wojciech Wegrzynski>, body of experience, we have this.

00:31:55.490 --> 00:32:00.799
<v Wojciech Wegrzynski>The article, Uh, examples or anecdotical proofs of the different planes.

00:32:01.250 --> 00:32:05.930
<v Wojciech Wegrzynski>You know, you've seen that happen once in a high rise building during commissioning.

00:32:06.170 --> 00:32:08.809
<v Wojciech Wegrzynski>Well, We don't really have a work worked out.

00:32:09.230 --> 00:32:11.690
<v Wojciech Wegrzynski>scientifical proof of how it works.

00:32:11.690 --> 00:32:12.950
<v Wojciech Wegrzynski>We don't have an understanding why.

00:32:13.519 --> 00:32:14.509
<v Wojciech Wegrzynski>It was like that.

00:32:14.509 --> 00:32:15.027
<v Wojciech Wegrzynski>And now.

00:32:15.176 --> 00:32:20.817
<v Wojciech Wegrzynski>we have a full-scale experimental facility that's armed up Measurement systems.

00:32:20.846 --> 00:32:21.406
<v Wojciech Wegrzynski>That's our top.

00:32:21.539 --> 00:32:23.910
<v Wojciech Wegrzynski>Arms up with all the automation that we need.

00:32:24.509 --> 00:32:28.170
<v Wojciech Wegrzynski>Finally, we can build evidence-based fire science.

00:32:28.170 --> 00:32:30.839
<v Wojciech Wegrzynski>And I think that makes me the most excited about this project.

00:32:31.740 --> 00:32:33.329
<v Grzegorz Krajewski>Verify what will happen?

00:32:33.333 --> 00:32:35.777
<v Grzegorz Krajewski>Depending on the, on direction of the Winchester.

00:32:36.106 --> 00:32:37.017
<v Grzegorz Krajewski>The wind speeds.

00:32:37.846 --> 00:32:40.186
<v Grzegorz Krajewski>The debt, what we have find out.

00:32:40.217 --> 00:32:41.517
<v Grzegorz Krajewski>during the commissioning tests.

00:32:42.047 --> 00:32:44.626
<v Grzegorz Krajewski>Then now we try to make it a little bit toward.

00:32:45.047 --> 00:32:45.717
<v Grzegorz Krajewski>And to research.

00:32:46.487 --> 00:32:49.696
<v Grzegorz Krajewski>And I think it will give us an answer how we should.

00:32:49.824 --> 00:32:53.304
<v Grzegorz Krajewski>Design that kind of system to make it fully safety for people.

00:32:54.443 --> 00:32:55.163
<v Wojciech Wegrzynski>We need to cut this up.

00:32:55.403 --> 00:32:55.933
<v Wojciech Wegrzynski>We're going down.

00:32:57.114 --> 00:32:59.483
<v Wojciech Wegrzynski>I guess we can talk about this possibilities for ages.

00:32:59.513 --> 00:33:00.034
<v Wojciech Wegrzynski>It's so exciting.

00:33:01.540 --> 00:33:02.787
<v Wojciech Wegrzynski>you can imagine our state of mind.

00:33:03.176 --> 00:33:05.586
<v Wojciech Wegrzynski>We've been building this for three In secrecy.

00:33:06.446 --> 00:33:06.717
<v Wojciech Wegrzynski>we've.

00:33:06.807 --> 00:33:10.213
<v Wojciech Wegrzynski>been designing this we've been pouring our hearts and, tears.

00:33:10.604 --> 00:33:15.374
<v Wojciech Wegrzynski>Into into, into building these, there was a lot of pain, including physical pain.

00:33:15.374 --> 00:33:17.953
<v Wojciech Wegrzynski>There was a lot of work, including heavy physical work.

00:33:18.374 --> 00:33:20.983
<v Wojciech Wegrzynski>But it looks like it was all worth it.

00:33:20.983 --> 00:33:21.253
<v Wojciech Wegrzynski>And.

00:33:21.763 --> 00:33:25.304
<v Wojciech Wegrzynski>Now to set up an experiment few hours and experiments is set.

00:33:25.574 --> 00:33:29.834
<v Wojciech Wegrzynski>And one day later you have results that no one ever has seen in the  fire science.

00:33:30.463 --> 00:33:32.713
<v Wojciech Wegrzynski>This is the magic of full-scale.

00:33:33.193 --> 00:33:34.394
<v Wojciech Wegrzynski>Experimental facilities.

00:33:34.814 --> 00:33:37.273
<v Wojciech Wegrzynski>Uh, as we said, we are on a to Renee.

00:33:37.844 --> 00:33:38.624
<v Wojciech Wegrzynski>The Europe.

00:33:39.134 --> 00:33:41.134
<v Wojciech Wegrzynski>Because she was going to Vilnius for the Baltic fire.

00:33:41.354 --> 00:33:41.503
<v Wojciech Wegrzynski>Uh,

00:33:41.534 --> 00:33:44.753
<v Grzegorz Krajewski>But starting from Monday, we are going to make  another test.

00:33:44.753 --> 00:33:45.054
<v Grzegorz Krajewski>So

00:33:45.203 --> 00:33:46.134
<v Wojciech Wegrzynski>of course, of course.

00:33:46.403 --> 00:33:48.384
<v Wojciech Wegrzynski>but, Uh, as we are sharing this.

00:33:48.564 --> 00:33:52.074
<v Wojciech Wegrzynski>with the world, I'll try to drop some links in the show notes too.

00:33:52.403 --> 00:33:54.339
<v Wojciech Wegrzynski>The current, presentations about the topic?

00:33:54.369 --> 00:33:58.450
<v Wojciech Wegrzynski>Uh, I think they Materials will be published on YouTube at some point.

00:33:59.109 --> 00:34:01.630
<v Wojciech Wegrzynski>And there are definitely available to anyone that registered to the conference.

00:34:02.170 --> 00:34:02.589
<v Wojciech Wegrzynski>So.

00:34:02.719 --> 00:34:06.767
<v Wojciech Wegrzynski>thanks, Four four openly sharing that at some point I'll I'll drop the links.

00:34:06.797 --> 00:34:08.146
<v Wojciech Wegrzynski>I'll make sure it's updated.

00:34:08.206 --> 00:34:10.157
<v Wojciech Wegrzynski>Uh, you can learn more about the facility.

00:34:10.726 --> 00:34:12.496
<v Wojciech Wegrzynski>And just, uh, follow us on Twitter.

00:34:12.527 --> 00:34:14.056
<v Wojciech Wegrzynski>Follow us on, on research gate.

00:34:14.447 --> 00:34:19.086
<v Wojciech Wegrzynski>You will be sure to find the newest materials related to this project.

00:34:19.179 --> 00:34:24.117
<v Grzegorz Krajewski>So, thank you very much and I hope it will be very useful for all of us all over the world.

00:34:24.356 --> 00:34:25.056
<v Wojciech Wegrzynski>Yeah, thanks guys.

00:34:25.246 --> 00:34:26.266
<v Wojciech Wegrzynski>, thanks for listening.

00:34:26.686 --> 00:34:30.376
<v Wojciech Wegrzynski>And that was a quick update on our newest.

00:34:30.503 --> 00:34:31.264
<v Wojciech Wegrzynski>Research and Deaver.

00:34:31.643 --> 00:34:33.114
<v Wojciech Wegrzynski>The experimental.

00:34:33.264 --> 00:34:34.103
<v Wojciech Wegrzynski>facility.

00:34:34.434 --> 00:34:40.434
<v Wojciech Wegrzynski>On small controlling corridors and its digital Uh, thanks for being here with us in the 5 cent show.

00:34:40.914 --> 00:34:45.443
<v Wojciech Wegrzynski>And now we're going back to enjoy the conference in beautiful Brno in Czech.

00:34:45.443 --> 00:34:46.324
<v Wojciech Wegrzynski>It's fantastic.

00:34:46.384 --> 00:34:47.523
<v Wojciech Wegrzynski>happy to see so many.

00:34:47.523 --> 00:34:50.253
<v Wojciech Wegrzynski>familiar faces in here meet new people.

00:34:50.373 --> 00:34:58.563
<v Wojciech Wegrzynski>So yeah, that's it for today's fireside show and see you back next Wednesday where we'll summarize the conference.

00:34:58.923 --> 00:35:02.704
<v Wojciech Wegrzynski>Because there's many CFD modeling and evacuation modeling updates.

00:35:02.737 --> 00:35:04.686
<v Wojciech Wegrzynski>that are absolutely worth to share.

00:35:04.746 --> 00:35:05.556
<v Wojciech Wegrzynski>with all of you.

00:35:05.706 --> 00:35:07.077
<v Wojciech Wegrzynski>Thank you guys, spice and thanks jiggles.

00:35:07.536 --> 00:35:08.286
<v Grzegorz Krajewski>Thank you very much.

00:35:08.376 --> 00:35:08.476
<v Grzegorz Krajewski>Bye-bye.
