摘　　要：利用CFD方法对200 km/h动车组软卧车包厢内的气流组织进行了模拟分析.首先,根据现车的空间布局和美工设计要求提出了4种可行的送风口布置方案,然后根据CFD模拟结果,分析了包厢内微风速、速度场和温度场均匀性以及热舒适性等指标,对4种方案进行了综合比较,确定了较优的方案,可为实车的空调系统方案设计提供依据.CFD method is used to simulate the air distribution in a compartment of EMU sleeping train. First, according to the space layout and design requested by art, four available schemes of air outlet placement are proposed. Then based on CFD simulation results, the indexes such as velocity, air flow evenness, temperature distributing evenness and thermal comfort are analyzed. The four schemes are comprehensively compared. Finally, the optimum scheme is determined on providing the basis with the air-conditioning system design.
