| 摘 要： | 所谓的逆风因子法就是分别用二阶精度公式计算出对流项和扩散项的贡献,然后按此两项贡献的比值来确定一个逆风因子,来保证对流扩散方程数值解的精度和稳定性。这种逆风因子法是作者在用有限元素法解不可压N-S方程中提出来的。本文将逆风因子法应用于在非正交曲线坐标系中用有限差分法解不可压N-S方程。

| Abstract: | The upwind factor method has found successful application in the finite element scheme. The purpose of this paper is to extend its application to solution of incompressible Navier-Stokes equations in non-orthogonal curvilinear coordinate system by the finite difference method. An effective velocity is introduced to keep the control equations in the computational domain as simple as in the physical domain. |
