某增压发动机冷却系统分析与验证

Analysis and Test of Cooling System for Turbocharged Engine

基于某增压发动机冷却系统布置原理及水套三维流阻边界,建立匹配该车型的冷却系统一维模型,进行典型工况下的分析,得到系统各支路流量分配情况,并进行冷却系统专项试验,验证仿真精度,评估仿真分析在冷却系统开发中的意义。

On the basis of engine cooling system layout and press loss of water jacket, 1D analysis model of cooling system is built. The flow distribution of each branches can be got by the simulation at rated power point. In order to verify the accuracy of simulation, the test of cooling system can be carried out ,and compared the data with simulation results.
