摘　　要：以某车型为研究对象,建立三维模型,并使用三维仿真软件Star-ccm+对模型进行仿真计算,通过相应车型在整车环境实验室中的试验数据进行验证,随后对该车型降温过程中流场及温度场分布进行分析。分析表明,送风射流区域、车顶后部下方区域以及乘员头部附近区域速度较高,乘员舱前部区域比后部区域温度高,下部区域比上部区域温度高。Three-dimensional model ol a specilied type ol car was established. The model was simulated by the three-dimensional simulation software Star-ccm＋ and validated by the experimental data ol the corresponding model in the vehicle environment simulation laboratory. Then the airflow distribution during the cooling process ol the model is analyzed. The analysis shows that the velocity in the air jet area, the area below the rear rool, and the area near the passenger head is higher than other area. The temperature in lront ol the passenger compartment is higher than that in the rear are-a , and the temperature in the lower area is higher than that in the upper area.
