With train speed increasing, the heat generation from its key equipment is growing as well and the cooling and ventilation of the equipment cabin become more and more important. In this paper, computational fluid dynamics (CFD) method is adopted to simulate the airflow and the temperature field in indoor and outdoor space of the equipment cabin when the train moves at 250 km/h in open space. The simulation...
In order to investigate the ventilation performance in the equipment cabin of a high-speed railway train, this paper uses computational fluid dynamics (CFD) method to simulate the air flow and temperature field in indoor and outdoor space of the cabin when the train moves at 250km/s in open space. The maximum average surface temperature of the heat generation equipment is 56.5°C. The results of this...
