Fire Science Show

When you think about battling wildfires, what is the image you see in front of your eyes? Probably an air tanker (at least that was what I saw...). After this interview, your optics will change about 180 degrees. Dr Cathelijne Stoof explained to me why strategies focused ultimately on fire resistance and suppression are deemed to fail, and why we need to learn to manage the risks in our forests. T...

Evacuation modelling is paramount in accounting for the human aspect in our fire modelling. But how is it developing? Where are we with our tools, and where are we heading with them? What are the most profound challenges related to the evacuation modelling? To answer these questions I have invited two renowned experts on evacuation modelling. Professor Enrico Ronchi from Lund University in Sweden...

Have you ever wondered who truly has the most power over the fire safety of a building? In my opinion, the answer is very simple - the Architect. This is due to two reasons. First is that the architect can affect the building shape, size, compartmentation, location of the openings in the building - things that are fundamental to the compartment fire dynamics. The second reason is that they make th...

Have you ever wondered how is a fire of a match or candle different from a wildfire? Or maybe rather, why is it different? What is it, that makes the fires at different scales behave in such a different manner? What are the phenomena that drive these fires, and are these the same phenomena across the scales? These are the questions I had in mind when starting the interview with a rising star of Wi...

We are living in a kind of weird time, where the most complex tool we have is at the same time the most commonly used (and abused one). The Computational Fluid Dynamics (CFD) modelling has brought us amazing capabilities in solving the flows within fires. But this power comes at a price - knowledge, resources, time... Sometimes we lack some of these (or all) and we turn the power tool into a gener...

In this episode, I had the pleasure and privilege to host dr Kees Both, the Technical Manager of Standards & Regulations in Etexgroup. Kees wanted to become a suspension bridge engineer, but his route went through a fire lab, and as he said - once you go into a fire lab, there is no way out. From a scientist, he has "evolved" into a research manager, project manager and someone, who...

What is the single most measured thing in fire science? The answer is easy - temperature. We use it everywhere - from learning material properties in TGA's to expressing conditions in compartment fires. We use it at the same time to define exposure conditions for our structures and the acceptance criteria within them. We even use it in evacuation studies to define the tenability criteria for...

Did you know that the standard temperature-time curve, which is the underpinning of the fire resistance of assemblies, is over 100 years old? Once you know that, you cannot stop but think about how this affects modern construction works. In this episode, I'm interviewing dr John Gales from York University, who has spent over a decade studying the historical origins of fire testing and the sta...

Why do we take certain decisions during an evacuation process? How do we choose the evacuation route? These are often affected by cognitive biases, which is the main theme of today's episode. With Dr Michael Kinsey we will discuss how biases can be used to understand known behaviours and model human behaviour in a more realistic way. A lot of focus is placed on the evacuation modelling, and h...

Zone modelling is a technique introduced in 1970's and 80's that has changed fire science. In my personal opinion, along with oxygen calorimetry and the development of FDS it may have been the most impactful tool of fire science. This is why I think its shameful it does not receive the same recognition today. With Colleen we go deep into the zone models, discussing the tool itself and th...

Everyone is talking about AI, but how can we really use it in fire safety engineering and firefighting? Prof Xinyan Huang of HK PolyU will explain his research in this field, and we can consider it as a time travel to the future. We touch on the ideas of AI and machine learning, and what does it really do (and what it does not do). We also investigate Xinyan's most recent research where AI wa...

In Episode 6, our host, dr Wojciech Wegrzynski, explains his experiences with modelling rapidly growing fires in car parks. Such fire growth may be typical for EV fires that originate in battery and pose a different set of challenges compared to "traditional" design fires used for car parks.  The height of the car park is discussed as the variable that has the largest impact on the overa...

Today I've talked to Roeland Bisschop, Project Manager in RISE, about his first-hand experience with battery fires. Roeland explained to me how do battery fires look from a scientific perspective, and how my perspective was kind of skewed by viral online videos. I've learnt a lot about fire propagation and products, as well as how to deal with fires that occured. This was a great talk, a...

Dr Matthew Bonner of the Imperial College London is one of the leading scientists touching on the subject of the fire safety of facades. His flavour is tackling the complexity through big data analyses and developing new ways to use AI to help us in future. His research has started few months before the Grenfell, and the tragedy has definitely made more eyes follow his studies. I think he has pass...

Let's do this. For the first time... Welcome to the Fire Science Show! My name is Wojciech Wegrzynski, and I'm with the Building Research Institute (ITB) in Warsaw, Poland. In this episode you will learn who I am, where do I come from and why I have decided to start a fire science podcast. I'm sharing my journey from a frontline CFD engineer to a professor at the ITB. I'm still...

Guillermo Rein is a recipient of ERC Consildator Grant on smouldering megafires. The most challenging source of founding, meant for the projects that can truly change the world. And his HAZE project is just like that - to study a phenomenon that accounts for more than 13% of anthropogenic CO2 emissions and takes the lives of thousands (millions?) of people every year. In this episode you will lear...

How do you know if a building is safe in fire or not? Usually through performing ASET-RSET analyses, in which you determine how and when the tenability criteria in the building are breached. This is what I discuss with dr Gabriele Vigne. We discuss the overall use of tenability criteria in fire science, and in more details, the use of visibility in smoke. --- LinkedIn Discussion thread --- https:/...

Hello world!!! This is the trailer episode for the Fire Science Show. I'm sharing with you some backstage news, a bit of origin story and an introduction to my great guests that have agreed to be interviewed by me.  I really hope you enjoy this. Thank you for your support, and I hope you will be here with me on 2nd June for the official start of the podcast. I have three episodes waiting for...
