摘　　要：空调车内气流组织研究是车厢内热环境控制的基础 ,合理的车内气流组织可有效地改善乘客的冷热舒适性。采用k -ε湍流模型对 2 5K型空调硬卧车内气流组织进行了数值模拟 ,研究了不同送风方式和送风参数下车内空气流场和温度场分布规律 ,并与实验结果进行了对照 ,两者基本一致。研究结果对于改善硬卧车内人体冷热舒适性提供了理论依据 。The air organization research is the basis of thermal environment control in air-conditioned compartment. Reasonable air organization can availably improve the passengers' thermal comfort. By k-ε turbulence model, the air fluid flow and heat transfer in air-conditioned hard-sleeper compartment are simulated numerically. The airflow field and temperature field are investigated in different air supply modes and air supply parameters. The comparison is carried out between the computed and the measured results of temperature and velocity fields. The agreement between them is quite well. A basis is given for the optimized design of air organization in the air-conditioned passenger compartment.
