具有导气屏结构的内燃机进气道流场的三维数值模拟研究

The Study of Three_Dimensional Flow in Intake Duct With Gas Leading Screen in Internal Combustion Engine

为了研究具有导气屏结构内燃机进气道内流动的特点 ,利用SIMPLE方法 ,采用交错网格 ,对其进行了数值模拟计算 .分析了其流场分布的特点 ,得到了一些规律性的结论 ,并与实验进行了对比 ,证明本文模型。

We calculated and analyzed the flow in intake duct with gas leading screen in internal combustion engine through studying the character of the flow in it and using the SIMPLE method and the staggered grid.We also compared the computational results with those of experiment.The comparison proved that our model and computation were correct.
