摘　　要：以开孔折流板矩形通道为例,对流体流经复杂几何通道进行数值计算时网格的划分方式进行了探讨,研究了对于同一计算模型,在不同工况下采用相同的网格划分时,网格独立性的考核标准。通过设置有两种类型开孔折流板通道的数值计算表明:对于同一计算模型,在不同工况下采用相同网格进行数值计算时,网格独立性的考核应该在高Re数工况下进行.The grid generation method for the complicated duct with the staggered perforated baffles is studied as a case,and grid independence standard is well analyzed when the same mesh is used in different Re number. On the numerical result of fluid flow through perforated baffled channel, it is found that grid independence should be carried out in the highest Re number when applying the same grid at different conditions.
