Fire Science Show Wojciech Wegrzynski

Is evacuation of a community during a wildfire largely different from evacuation of a building? How much of the knowledge from the building fires is directly useful in planning and managing such an event, and what stuff is completely different? These are the lead questions for my today's interview with prof. Enrico Ronchi from Lund University and dr Max Kinateder from National Research Council Canada. Both guests currently research the evacuation layer of the WUI problem – starting...

In the episode 10 of fire fundamentals together with David Morrisset, a nearly graduated PhD student from the University of Edinburgh, we explore the intricate dynamics of flame spread and its crucial role in fire safety engineering. David helps us differentiate between the two primary modes of flame spread, concurrent (imagine upward spread) and opposed (imagine downward spread), and explains how understanding these mechanisms can significantly enhance building safety and fire risk mitigatio...

With two Directors at NFPA - Michele Steinberg and Birgitte Messerschmidt, I'm trying to find an answer to a burning question - "what really is the WUI problem?" The WUI is not just a line on a map with an X distance from the forest... In this episode we try to define what it is, and who is in danger. Instead of our usual conversations looking into characteristics of burning forests, or seeking the impact of detailing in construction, in this episode we try to take a birds eye view and identi...

In today's Fire Science Show, we talk about how boundary conditions can make or break your fire simulation models. We'll explore boundary conditions' fundamental role in defining how simulations interact with their environments and how mastering these can lead to more accurate and reliable fire simulation models. I hope we break down some complex topics into manageable insights. Also, I hope we've turned something really boring into an interesting and fun episode. We discuss:1. Boundaries int...

A critical velocity episode... who would have thought? Even though I'm not an enthusiast of this approach, I have to admire the new science and researchers striving to improve it. This week I welcome Conrad Stacey and Michael Beyer from Stacey Agnew to talk about their recent developments. We'll take you through the historical development of this concept since its inception in 1958, examining key variables like tunnel height and heat release rate along the way. We go into the Memorial Tunnel ...

What if you could predict the last possible time to evacuate your community before a wildfire wreaks havoc? What if you had that knowledge years before the wildfires happened and built up your preparedness based on this knowledge? What if you knew how this boundary changes with wind, dry weather and direction? I think you get a knowledge-based decision model, and that is exactly what my guests today have been looking for.Join us as we explore this cutting-edge approach with Imperial Haz...
