摘　　要：为了大幅度减少试验工作量建立了中冷器的CFD计算模型,采用标准k—ε湍流模型对中冷器的湍流流动和换热进行了仿真计算,对增压空气侧阻力性能和空气散热量进行了数值分析。仿真计算值与试验测试数据趋势吻合良好,该仿真方法可以有效地进行中冷器结构参数变化对流动传热性能的影响研究,有利于缩短设计周期和减少设计成本。The intercooler for high-power diesel locomotive is demanding with the air flow resistance.Traditional analysis method of resistance performance relies on a large number of experiments.In order to reduce the experiment workload,this paper established the CFD calculation model of intercooler with standard k-ε turbulence model for simulating turbulent flow and the heat transfer.The resistance performance of pressurized air side and the air's heat dissipation were analyzed by CFD calculation.The simulation calculation results are in good agreement with experimental test data.This method can be effectively used to study the flow and heat transfer performance when intercooler structure parameters are changed and so the design time and costs will be reduced.
