摘　　要：给出了螺旋与切向气道相组合的进气系统结构网格生成的一种拓扑分块方案及实现过程 ,求解椭圆型方程生成各块内三维网格 ,用Hilgenstock方法修正源项 ,并利用分块粘接技术生成了组合进气管道三维分块结构化贴体网格 .A multi-block structured grid generation system for complex combination intake manifold was presented. The volume grid in each block was generated by solving elliptic partial differential equations and the source terms in equations were corrected by Hilgenstock method. Each block grid was patched together and an integrated three-dimensional grid of combination intake manifold was generated. The flow numerical analysis indicated the multi-block grid was better.
