Numerical Simulation on the Temperature Field in an Equipment Cabin of a High-speed Railway Train

摘要

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 ℃. The results of this study provide suggestions for the arrangement of the equipment, the design of the ventilating grilles, and selection of fans for the equipment cabin of the high-speed railway train.
