摘要
Abstract
Surface pressure distribution of air conditioning equipment at the top of train has important engineering application value for reasonable selection and layout of the air-conditioning ventilation new-air intake and exhaust gas outlet.By using 3D,steady state incompressible Navier-Storkes equation and two equations k-ε turbulent model,the numerical simulation of an eight section marshalling EMU running in open air was carried out by finite volume method.Surface pressure distributions of air conditioning equipment at the tope of train along the longitudinal and width direction of the train were gained.At the same time,the recommended setting position and principle of the air-conditioning ventilation new-air intake and exhaust gas outlet were put forward.关键词
