Etude numérique de l'influence des véhicules sur la destratification des fumées d'un incendie en tunnel

Abstract : This article show the results of four CFD simulations made with FDS software [1]. This numerical study deals with the influence of vehicle on stratification loss phenomena in tunnel fire. First evaluations on this influence are then proposed. A comparison is systematically established between the case with vehicles and the case without vehicle. The results shown here after concern two different heat release rate currently used in French hazard studies for road tunnels. Thèse first results have shown that vehicles stopped in the near field upstream improve the stratification by reducing theé rebound of smoke plume on the roof. In opposite, vehicles in the far field upstream fire increase the size of turbulent structures, which induces a speed up of stratification loss phenomena.
