本文首先讨论简化Navier-Stokes IFT方程组的有限元离散方式,然后对其广义解进行分析,并从而利用与之相匹配的各向异性张力单元对流函数—涡量方程进行计算。通过平板层流和台阶绕流两个算例的分析,证明这种与IFT理论相匹配的有限单元算法是成功的。

A scheme of finite element discretization of simplified N-S equations is studied in the paper firstly , then the generalized solution is analyzed. The stream function-vorticity equations are computed by the method of anisotropic tensor force finite element. Two examples which are the laminar flow between two plates and the back ward-facing step flow are studied. This finite element methed w...
