Abstract
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.
