采用结构重叠网格方法对栅格翼导弹的粘性流场进行了数值仿真计算,相对于单一结构网格而言,该方法不但降低了网格生成难度,提高了网格质量,而且大幅度降低了网格数量,计算结果表明该方法是可靠有效的。
採用結構重疊網格方法對柵格翼導彈的粘性流場進行瞭數值倣真計算,相對于單一結構網格而言,該方法不但降低瞭網格生成難度,提高瞭網格質量,而且大幅度降低瞭網格數量,計算結果錶明該方法是可靠有效的。

The numerical simulation of the viscous fluid field around grid fins using overlapping structured grids is introduced. Compared to pure structured grids, the overlapping structured grids are not only much easier to be generated with high quality, but the total number of cells is also smaller. The re- suits of the numerical simulation show the method is effective and reliable.
