ABSTRACT
ABSTRACT: In subway tunnel fire, the greater possibility is the fire on the train, the emergency response is to run the train with the fire to the front of the station as far as possible. The key points to run the on-fire train in the tunnel are the intensity of fire and the train velocity. This paper adopts a fire prototype to perform a model experiment of the train fire in a 1:8 subway tunnel model. By using Computational Fluid Dynamics (CFD), the moving train with fire in the center is simulated in the tunnel by the moving mesh function of STARCD software. Through studying the influence of the different train speed and the heat release rate on the temperature distribution in the tunnel, the rule of smoke temperature distribution of the moving on-fire train in the tunnel is pointed out.
