摘　　要：文章利用商用三维计算流体力学(CFD)软件和一维仿真软件相结合,对某型车机舱内外流场进行模拟分析,得到中冷器周围流场特性,并对流场进行优化,提升通过中冷器的风量。然后通过一维软件对中冷器在整车上的性能进行分析并与实验数据进行对比,结果表明,分析结果与实验结果吻合度较高。The flow field in engine room and around inter-cooler is simulated by using 3D CFD software. Then the performance of inter-cooler is simulated by using 1D simulated soitware. By optimizing the airflow around inter-cooler and engine room, the air flow rate through inter-cooler and its performance are improved. The numerical simulation results are in good agreement with experimental results.
