摘　　要：　应用FLUENT软件对车用叉流板翅式机油冷却器两侧流体的流动进行了数值模拟,紊流模型采用标准的K ε湍流模型,翅片侧采用多孔介质模型进行简化。结果表明,油侧的流量分配比较均匀,而水侧很不均匀,为叉流板翅式机油冷却器的设计改进指明了方向。2-side fluid flow field in a plate-fin oil cooler was simulated with FLUENT code. The standard K-ε model was used as turbulence model, while the domain of fins was simplified as porous media. The simulation result shows the mass flow rate of oil side is fairly uniform ,while that of water side is very non-uniform, which can help the design and optimization of cross-flow plate fin oil cooler.
