143 - Design fire generator with Greg Baker

March 19, 2024 21:00 - 53 minutes - 36.9 MB

Imagine if we had a tool that we could use to design a design fire. Instead of simply assuming fire growth characteristics by slapping the alpha-t2 function, use a tool that could tell us which items in a compartment burn and what the characteristics of that fire are. I would say this dream is shared among many fire safety engineers - I think we can all agree that we could use such a tool. Today's guest, Dr Greg Baker, has shared this dream and built a tool like this within his PhD at the U...

143 - Fire Fundamentals pt 7 - CFD simulations of fires

March 12, 2024 23:00 - 48 minutes - 33.6 MB

In today's fire fundamentals episode, I have chosen a difficult job: explaining how CFD modelling works without the ability to put a single equation out there! It's much tougher than I thought! I hope I've done a decent job, though. I am trying to fill out this niche of talking about CFD at an approachable level. I've noticed there is a ton of 'introductory' level resources about modeling. Still, they usually very quickly go into mathematical formulations instead of explaining in plain lan...

142 - Uncertainty in fire measurements with David Morrisset

This week, I am meeting up with Imperial Hazelab's Harry Mitchell, who is finalizing his PhD thesis on mass timber fires and, quite uniquely - including the smouldering phenomena in those fires. As a part of Code Red experiments run by Arup, Imperial College London and Cerib (which you can learn more about from episode 111 with Panos Kotsovinos)  Harry has performed observations of formation, growth and decay of smouldering "hot spots" for up to 2 days after the fire. Based on that, conclus...

140 - Development and implementation of the SBI test with Rudolf van Mierlo

February 21, 2024 07:00 - 51 minutes - 35.2 MB

Tests in the world of reaction to fire are supposed to be representations of real fire scenarios, allowing us to grasp the characteristics of building products against them. While for the worst scenario (flashover fire) or the smallest ignition source (small flame), the definition is pretty straightforward. However, creating the intermediate method that the entire Europe would agree on was a bumpy ride. Our latest episode is a treasure trove of knowledge detailing the birth and maturation of...

139 - Wind and Fire Interactions for Safer Open Car Park Design

February 13, 2024 22:00 - 46 minutes - 32 MB

I've finished my first large research grant! I guess that makes me a 'real' scientist now. Came here today to share some most interesting aspects of this project with you. Not going to bore you all about the wind and fire interaction physics (hey, there is an entire episode 50 devoted to that!), but rather talk about challenges and stuff that perhaps will matter if you would like to engineer a case similar to one we have studied. So in this podcast episode, we will go into: How our framewo...

138 - Getting ready for the Wildfires in Northern Europe with Nieves Fernandez-Anez

January 30, 2024 22:00 - 53 minutes - 37.1 MB

It is interesting to see changes in our profession that happen directly in front of our lives. Climate change and in consequence the changes in the wildfire patterns are one such obvious shift. In Poland, we do not ever have a ‘wildfire’ season, and I was kind of surprised when I discovered this is a thing in the South or in other parts of the world. Unfortunately, we do not have it *yet*. Some years ago devastating wildfire season happened in Sweden. There has been an emergency in northern ...

135 - Contemplating a design fire for car parks

January 09, 2024 23:00 - 49 minutes - 34 MB

In episode 48, my guest Mike Spearpoint said that in mid '90s, he participated in experiments on vehicle fires, as at that time, there were doubts if the design fires of that time (developed in the '80s) were representative of modern cars. Fast forward 30 years ahead, and we seem to be in a very similar situation. We have limited knowledge on vehicle fires, most coming from very old studies that have used even older vehicles... And we have a fleet that consists of larger vehicles, gravitatin...
