The finite volume approach in space, the three order Runge Kutta method in time and a "law of the wall" for the solid wall condition were used.
数值离散时，将时间与空间分开进行处理，空间上的离散采用有限体积法，而时间上的离散则用三阶龙格-库塔法，对固壁边界的处理使用了“壁函数”法。
The main purpose of the virtual grid is to convert a solid wall boundary condition into an interface condition while no fluid flow computations are conducted within the virtual grid.
虚拟网格为紧贴物面的面网格，它的作用是将物面边界条件传递给其它网格的边界面，而其本身不作流场计算。
The finite volume approach in space and predictor-corrector method in time is used, and "partial slip condition" is applied to the solid wall boundary condition.
数值计算采用有限体积法和预测校正法，固壁边界条件采用“部分滑移条件”。
