CFD simulations for fully-developed fires in a room under different ventilation conditions

Fire experiments were designed for studying the characteristics of fires in rooms under different ventilation conditions. Parameters such as heat release rate, fuel total mass loss, temperature, airflow distribution, and fire duration were used to determine the effect of different ventilation schemes on fire dynamics. The fuel package consisted of a mock-up sofa made of polyurethane foam and two wood cribs placed under it to provide additional fuel load to sustain a fully-developed fire. The Fire Dynamics Simulator (FDS) Version 5 was used to conduct the numerical simulations.Des incendies exp\ue9rimentaux ont \ue9t\ue9 con\ue7us aux fins de l'\ue9tude des caract\ue9ristiques des feux \ue9clatant dans des pi\ue8ces soumises \ue0 diff\ue9rentes conditions de ventilation. On a utilis\ue9 des param\ue8tres tels que le taux de d\ue9gagement de chaleur, la perte massique totale de la charge combustible, la temp\ue9rature, la distribution du flux d'air et la dur\ue9e de l'incendie pour d\ue9terminer quels \ue9taient les effets des diff\ue9rents syst\ue8mes de ventilation sur la dynamique des feux. La charge combustible utilis\ue9e \ue9tait une maquette de canap\ue9 en mousse de polyur\ue9thane situ\ue9e au-dessus de deux (2) b\ufbchers en bois. On obtint ainsi une charge combustible additionnelle pouvant entretenir un incendie \ue0 son maximum d'activit\ue9. Le Fire Dynamics Simulator (FDS), version 5, a \ue9t\ue9 utilis\ue9 pour les simulations num\ue9riques.Peer reviewed: YesNRC publication: Ye
