Fire Science Show is connecting fire researchers and practitioners with a society of fire engineers, firefighters, architects, designers and all others, who are genuinely interested in creating a fire-safe future. Through interviews with a diverse group of experts, we present the history of our field as well as the most novel advancements. We hope the Fire Science Show becomes your weekly source of fire science knowledge and entertainment. Produced in partnership with the Diamond Sponsor of the show - OFR Consultants

143 - Fire Fundamentals pt 7 - CFD simulations of fires
In today's fire fundamentals episode, I have chosen a difficult job: explaining how CFD modelling works without the ability to put a single equation out there! It's much tougher than I thought! I hope I've done a decent job, though.
I am trying to fill out this niche of talking about CFD at an approachable level. I've noticed there is a ton of 'introductory' level resources about modeling. Still, they usually very quickly go into mathematical formulations instead of explaining in plain language what is the purpose of specific models or modelling approaches.
In this episode, you will learn about:
- what is Computational Fluid Dynamics modelling;
- what is the role of conservation laws of mass, energy and momentum;
- what is turbulence, and why it impact our calculation so much;
- what are the common families of turbulence models (RANS and LES), and how do they differ from each other;
- what are sensitivity studies, and how does one choose an appropriate mesh for their problem?
If I had one book to recommend, it would be this book by Bart Merci and Tarek Beji.
If I had one paper to recommend, it would be this paper by Kevin McGrattan (open access).
