In the 16th part of the Fire Fundamentals series, we invite Randy McDermott from NIST to join us for a deep dive into turbulence and its critical role in fire dynamics modelling. We explore the physics behind turbulent combustion and how it fundamentally shapes fire behaviour, plume dynamics, and simulation accuracy. In this episode we cover: Defining turbulence as the enhancement of mixing and heat transfer through the creation of eddies and instabilitiesUnderstanding length scales in turb...
