• 272 - How to add wind to fire CFD analysis?

  October 7, 2026 · 46 min

  In this episode I take you into practicality of introducing wind into fire safety engineering considerations, and focus on it's implementation as a part of fire oriented CFD analyses. In here, we dig into why wind is tied to so many…

• 271 - pyFDS-Evac with Mohcine Chraibi

  September 30, 2026 · 56 min

  Smoke does not just slow people down, it changes what they believe is even possible. That simple idea is why we get so excited about pyFDS-Evac, an open source workflow that connects Fire Dynamics Simulator (FDS) results directly to modern…

• 270 - How the Cone Calorimeter took over with Marc Janssens

  September 23, 2026 · 49 min

  A tool doesn’t become a global workhorse because it’s clever. It becomes a workhorse when different labs can run it, calibrate it, compare it, and trust it. It is a very long road from the invention to widespread use. And I got the chance…

• 269 - Fire investigations and the scientific method with Vincent Brannigan

  September 16, 2026 · 59 min

  A fire scene looks like a puzzle, but it’s a puzzle where the pieces melt, burn, and get hauled away before anyone can measure them. On the 25th anniversary of 9/11, I sit down with Professor Vincent Brannigan to ask a questions - does a…

• 268 - Is critical velocity that critical?

  September 9, 2026 · 53 min

  Critical velocity is supposed to be the clean moment when tunnel smoke control flips from unsafe to safe. But after too many real projects and too many review battles, I am very sure that such a single number cannot be a sole proxy of what…

• 267 - Modelling Fire Growth with Stephen Welch

  September 2, 2026 · 1 hr 2 min

  Pretty CFD flames are something we got used to, but they usually are a product of our design assumptions - the design fire. While they give us a lovely illusion of being "real" fires, predicting real compartment fire growth is a completely…

• 266 - Compartment fire framework with Vinny Gupta

  August 26, 2026 · 1 hr 11 min

  A compartment fire is more than just “a fire in a room.” The moment flames, smoke, and heat are trapped by walls and fed through openings, the physics changes and so do the hazards we design for. We sit down with Dr. Vinny Gupta…

• 265 - How fires can lead to a nuclear winter? with Stephen Welch

  August 19, 2026 · 1 hr 7 min

  As a kid of 80s and 90s, a lot of the pop culture was around the post-apocalyptic scenarios following a nuclear exchange. I always thought a nuclear winter is a consequence of atomic bombs falling down, but now as a fire researcher I've…
