| Abstract: | In this paper,the influence of the train's piston effect on platform's environment is simulated by using Computational Fluid Dynamics(CFD) method.The three dimensional air velocity distribution and its influence on the comfortable senses of passengers on subway platform are presented during a single train entering and departing processes.On basis of the simulation,air exchange rates caused by piston effect are calculated.At last,some problems which should be considered in heating,ventilation and air-conditioning(HVAC) system design in the future are pointed out according to the simulation results and analyses. |
