| 摘 要： | 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．

| Abstract: | The blocked coupling technique is used to generate the three dimensional non orthogonal body fitting grid for the calculation of a 3 D flow field in compact exhaust manifolds of an MPC turbocharging system. The method described will guarantee that during grid generation the grid lines going through the boundary surface are smooth and continuous. Another feature of the method is that the grid density in the inner region can be controlled either by the grid density at the boundaries or by specifying the included angles between the grid lines at the boundaries. |
