237 - Fire Fundamentals pt. 18 - Explosions with Ali Rangwala and Lorenz Boeck

Welcome back to Fire Fundamentals! Today with prof. Ali Rangwala from WPI and dr Lorenz Boeck from Rembe and WPI we take the world of explosion protection engineering. In this episode we touch: • distinguishing fires and explosions by time scale and damage mode • taxonomy of explosions by energy density and deposition time • hybrid mixtures in coal mines and turbulent burning velocity • severity metrics for gases and dust deflagration index for reactivity • explosion sphere testing, ign...

260 - Fire safety in a carbon budget with Cecilia Wetterqvist and Axel Mossberg

260 - Fire safety in a carbon budget with Cecilia Wetterqvist and Axel Mossberg

A carbon budget can feel like a hard wall in modern building design, and once you treat CO2 as currency, everything starts competing for a slice of it. The problem is that fire safety systems often sh...
