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

episode 27: 027 - Travelling fires with Guillermo Rein
If you have ever learned about the compartment fire dynamics framework, have tried zone modelling or any kind of fire modelling, you have probably noticed that as the compartments get bigger, the less uniform conditions inside are. At some size, the flashover or a "single-zone" model theories just break, MQH equation does not give a reasonable solution and the fire seems not capable of growing to a huge size... But yet, they destroy buildings. Local fire exposure may be damaging to structural elements in the same way as a flashover is. And that is how we considered it for many years...
But there was a gap. Something between a localized fire and a flashover'd fire. For many years we've seen it, but we have not acknowledged it fully untill it was given a name - the Travelling Fire. In today's episode, I have invited prof. Guillermo Rein of Imperial College London, to tell us the origin story, recent developments and future plans related to this methodology. This should be interesting to all - from fire scientists to engineers. IMHO, a well invested hour of your time!
Make sure to connect with Guillermo on socials:
- Twitter
- LinkedIn
and with his group - Imperial Hazelab (also on Twitter).
Guillermo has published 200 research papers, and among them many landmark pieces on travelling fires that I recommend:
- Travelling fires for structural design (2012) with J. Stern-Gottfried
- Improved formulation of Travelling Fires (2015) with E. Rackauskaite et al.
- Improved Travelling Fire Methodology - iTFM (2017) with E. Rackauskaite
- Computational analysis of thermal and structural failure criteria of a multi-storey steel frame exposed to fire (2019) with E. Rackauskaite et al.
- Flame extension and the near field under the ceiling for travelling fires inside large compartments (2020) with M. Heidari et al.
- Fire Experiment Inside a Very Large and Open-Plan Compartment: x-ONE (2021) with E. Rackauskaite et al.
- Thermal Response of Timber Slabs Exposed to Travelling Fires and Traditional Design Fires (2021) with F. Richter et al.
