采用分块耦合技术生成了ＭＰＣ模块多分支联接的三维非正交贴体网格，为进行流场计算作了必要的准备．所介绍的网格生成方法保证了在分块生成网格时穿过分界面的网格线是光滑连续的，并且可通过边界面上网格疏密或者规定边界面上网格线之间的夹角来控制内部区域的网格疏密． The three-dimensional non-orthogonal grid of multi-branch MPC module was generated by the block coupling technique, which made the necessary preparation for the flow field calculation. The introduced grid generation method ensures that the grid lines passing through the interface are smooth and continuous when the grids are generated in the block, and the grid lines passing through the interface can be smoothly and continuously formed by the grid spacing on the boundary surface or the grid line on the boundary surface Control the internal area of ​​the grid density.
