摘　　要：应用FLUENT软件对高速软卧车包间内的温度场和气流场进行了数值模拟,基于非稳态的双方程湍流模型,分别对夏季、冬季送风情况下包间内的温度、速度分布进行分析.研究结果表明,客室空调原送风量分配方案对应的温度场和气流场不能满足标准要求.通过调整客室内各个部位的风量,温度场和气流场的计算结果基本满足UIC553的要求.根据以上的仿真计算结果对目前的通风系统提出了合理的改进建议.Air temperature and speed fields in a high-speed soft sleeper car were simulated using FLUENT software. Based on non-steady-state two-equation turbulence model, the air distribution conditions including temperature and velocity summer and winter were analyzed. The simulation result could not satisfy the request standards both on the temperature and speed fields in the original air flow rate distribution. Through adjusting the flow rate distribution in the passenger car, the result satisfies the UIC553 standard on air distribution. A reasonable proposal is proposed for the ventilation system according to the results of the computer simulation.
