【摘要】 介绍了对车用柴油机气气中冷器内对流换热过程的三维数值计算的实施过程及结果分析，其热气通道的传热边界条件是通过对沿流程单位长度段内的能量平衡分析而推导出的函数关系来表征的。用ＳＩＭＰＬＥＳＴ算法对流动传热过程进行了三维数值计算。对比了不同传热边界条件的计算结果，按本文推导确定的边界条件计算的结果与实测结果取得了很好的吻合，为借助于数值计算分析中冷器传热过程奠定了基础更多还原

【Abstract】 D numerical process and calculation results for the heat transfer process in a vehicle air to air intercooler are presented in this paper.Heat transfer boundary conditions are described with a function deduced from energy balance on unit length of a hot air duct.SIMPLEST method is used in solving the mathematical model.The calculation results are agreed with those obtained in experiment.It builds up the base for analysis of the heat transfer process in intercoolers through numerical method.更多还原
