摘要:
 空调通风系统对城际车辆微风速、温湿度等产生重要影响,直接影响乘客的热舒适性。建立某城际车辆客室空调通风系统的三维全流场几何模型,将SIMPLE 算法与Realizable k-ε 湍流模型相结合,采用流量进出口边界,完成整车客室空间全流场仿真计算,通过试验测试验证仿真结果的准确性,并进一步对客室流场分布、微风速、速度场、温度场等进行深入分析。研究表明,整车客室空间内的流场及温度场分布整体较均匀,满足工程设计要求。
Abstract:
 In intercity vehicle, the air conditioning and ventilation system has an important impact on breeze speed, temperature and humidity of, which directly affects the thermal comfort of passengers. The three-dimensional full flow field geometric model of the air conditioning and ventilation system in the passenger compartment of an intercity vehicle was established. By combining SIMPLE algorithm with the Realizable k-ε turbulence model, and adopting the flow inlet and outlet boundary, the simulation calculation of the full flow field in the passenger compartment of the whole vehicle was completed. The accuracy of the simulation results was verified by the test, and the flow field distribution, breeze speed, speed field and temperature field in the passenger compartment were further analyzed. The results showed that the distribution of flow field and temperature field in the passenger compartment of the whole vehicle was even, which met the requirements of engineering design.
