摘　　要：采用分块粘接的网格生成技术,利用求解Poisson方程生成螺旋气道和切向气道相组合的进气系统以及缸内的三维贴体网格。用任意拉格朗日—欧拉(ALE)法对该组合进气系统进行了稳态流场的数值模拟。分析了组合进气道内的气体流动特性,为理解组合气道结构形状对进气流动的影响提供了有力的依据。A multi-block structured body-fitted grid for complex combination intake system with solving Poisson equations is built.The steady state calculations on flow system are numerically simulated using the arbitrary Lagrangian-Eulerian method,The flow characteristics in combination intake system have been analyzed,which provide strong basis for understanding the effect of combination intake structure upon inflow stream.
