257 - Fire Fundamentals pt. 21 - Radiation with Simo Hostikka
In this episode of fire fundamentals we sit down with Professor Simo Hostikka from Aalto University to cover radiation in fires, both from the angle of physical phenomena and ways to model it. In this episode we cover following topics: feel less mysterious, from blackbody basics and role of radiation actually does inside the CFD N-S equation. Spectrum and emissivity to real engineering outcomes like heat flux, tenability Radiation’s two roles in fire CFD: target heat flux and the gas energy sour

256 - Modelling turbulent combustion in fire CFD with Bart Merci
While we can get pretty far with a very simple approximation of what a fire is in our fire cfd, at some point our simplications are not enough. And there is a plenty of features and phenomena, for which we simply need a better tool to handle - carbon monoxide, soot, extinction, flashover behavior, and what happens when ventilation disappears. At the IAFSS symposium, we sit down with Professor Bart Merci (Ghent University), fresh off delivering the Howard Emmons Invited Plenary Lecture, to talk

255 - Timber load bearing capacity in fire from nano- to megascale with Felix Wiesner
A timber column can survive the heating phase of a fire resistance test and still collapse later, after the flames are gone. We know there is so much more to structures in fires than the test demonstrates, but how much exactly do we know about timber nowadays? In this episode we try to dive deeper and discuss mass timber fire safety, structural fire engineering, and what a fire resistance rating does and does not tell us. I’m joined by Dr. Felix Wiesner from the University of British Columbia, t

254 - Communicating fire science with firefighters, with Steve Kerber
Fire science should have its place at the fireground, yet I've learned how hard it is to communicate it with the key stakeholder - the firefighters. It's not my isolated experience, and that tension drives our conversation with Steve Kerber, Vice President at UL Research Institutes Fire Safety Research Institute (FSRI). Today we dig into the real craft of communicating fire dynamics to firefighters without losing the truth of the science. We talk about why experience alone can mislead when e...
