摘　　要：基于k-ε两方程模型,利用PHOENICS软件,在实验检验的基础上对列车车厢空调各种气流组织方式进行了模拟,并对其舒适性及经济性进行了评价.结果发现:传统的车顶条缝送风及格栅送风为较好的送风方式;椅背送风由于其独特的优点可推广应用;小桌下送风由于很难达到舒适要求不宜采纳.The simulation on the air distribution in an air conditioned railway carriage was carried out by using software PHOENICS based on the model of k-Ε. The validation of the simulation was verified by comparing the calculation result with that of the prototype experiment. Then various kinds of air distribution in the carriage were simulated and the evaluations on the thermal comfort and economy were conducted. It is found that the conventional slotted inlet and grid inlet on the ceiling of the carriage are suitable for air supply, the chair back inlet can be popularized for its special advantages, and the inlet under the little table is not worth for applying for its poor thermal comfort situation.
