摘要
本文介绍有限解析法的一种新构想,并将本方法用于求解不可压缩粘性流体流动的N-S方程,采用贴体坐标,雷诺数达1000,计算结果表明本方法是有效的。正确的。
The present paper describes an improved finite element method and it has been used to N-S equation of incompressible viscous fluid. With this method and body-fitting coordinate system, the flow over a circular cylinder was simulated numerically up to Re=1000. The results show that the present method is an efficient method to solve N-S equation.
