摘　　要：建立了车用柴油机中冷器冷却空气侧波翅片通道的湍流数学模型,应用CFD(计算流体力学)方法对中冷器空气冷却侧阻力性能进行数值分析,得到阻力系数与平均流速拟合函数,可为中冷器的设计和优化提供有益的参考.A turbulent flow mathematic model is established for offset fin channels at cooling air side of a inter-cooling of an automobile diesel engine. The resistance performance for a inter-cooling at air cooling side are numerically calculated. And fit function is gained between resistance coefficient and average velocity of flow. The results are of valuable reference for design and optimize.
