The influence of moving train on subway station fire is simulated by Computational Fluid Dynamics in this paper. The characteristics of piston effect produced by one racing train and two trains racing vis-a-vis are studied respectively. On the basis of simulation, a three dimensional smoke velocity and temperature distribution are investigated. Simulation results show that the air velocity field is disturbed and smoke is stretched to further distance along the platform by a moving train. The smoke layer presents a 'S'-shaped distribution when the piston wind is caused by two trains flashing vis-à-vis, indicating that the smoke layer on the subway platform is diffused and it might be harmful for evacuation.
Keywords:fire; subway station; moving train; piston wind; numerical simulation
