In this paper, the fire phenomena of compartment in YW25K train with different velocities is simulated and investigated by using Large Eddy Simulation (LES), Smagorinsky-Yoshizawa Mixed Sub-grid Scale model (SGS) and the mixture-fraction combustion model by the infinite fast chemistry kinetics. Based on the relative velocity theory, the different train running speeds are provided by the simulated wind tunnel velocities. The expanding of fire, the smoke movement and the temperature distribution in the compartment are analyzed. Some recommendations for better fireproofing design and safety management of train compartment are obtained.
