006 - EV's, rapid fires and car parks

In Episode 6, our host, dr Wojciech Wegrzynski, explains his experiences with modelling rapidly growing fires in car parks. Such fire growth may be typical for EV fires that originate in battery and pose a different set of challenges compared to "traditional" design fires used for car parks.  The height of the car park is discussed as the variable that has the largest impact on the overall safety of the facility.I discuss the aspects to consider when analysing the safety of a car park for electric vehicles and go in-depth into a large CFD project carried at the ITB in the last year. I hope my views will be useful to fellow fire safety engineers tackling how to provide safety for car parks fit for EV's!For this episode, a companion paper illustrates some of the HRR curves used in the experiment and briefly summarises the findings: https://www.sfpe.org/publications/magazine/fpeextra/fpeextra2021/fpeextraissue64--- LinkedIn Discussion Post ---https://www.linkedin.com/posts/fire-science-show_006-evs-rapid-fires-and-car-parks-fire-activity-6813335411184738304-M3dh--- Useful links ---The viral video mentioned in the episode:https://www.youtube.com/watch?v=sAQlLu5ttOkShort paper on the issue discussed in the episode: https://www.sfpe.org/publications/magazine/fpeextra/fpeextra2021/fpeextraissue64Discussion on modelling vehicles (as obstacles) in car parks:https://panel.sft.cnbop.pl/storage/ba77bcb7-0f79-4b14-a595-e36f60c7e3b0FEMTC 2021 presentation on the multiparametric simulation project, going a bit more in-depth in how the study mentioned in the episode was performed:https://www.youtube.com/watch?v=XsjqV1g6PYY----The Fire Science Show is produced by the Fire Science Media in collaboration with OFR Consultants.
