采用k-ε湍流模型对列车车厢内气流进行数值模拟需要消耗大量的计算时间，为此，提出了采用零方程湍流模型对列车车厢内的气流组织进行数值模拟；分别采用零方程湍流模型与k-ε湍流模型对列车车厢内的空气流动及传热进行了数值计算，经分析比较可知，该两种湍流模型的数值计算结果吻合程度较好，采用零方程湍流模型可大大缩短计算时间，利用其简单、快捷的特点，可以为列车空调系统的工程设计提供简便的数值模拟方法。

It will cost much time for numerical simulation of air distribution in train compartment using k - ε turbulence model, so zero equation turbulence model is used for simulating airflow in train compartment. In this paper, zero equation turbulence model and k - ε turbulence model were applied for numerical simulation of indoor fluid flow and heat transfer respectively. By comparison, the results come from these two. methods are inosculated very well, and the time cost by zero equation turbulence model is very little. So zero equation turbulence model has the merit of simpleness and quickness, it will provide a simple and convenient numerical simulation method for the design of train air-conditioning system.
