摘要: Cockburn & Shu[1] 在1988年提出了一种TVB Runge-Kuta局部投影的间断Galerkin有限元方法应用于Euler方程的求解,并取得了成功。文章将该方法进一步应用到Navier-Stokes方程的求解。

关键词: 间断Galerkin法, Navier-Stokes方程

Abstract: The RKDG method, proposed by Cockburn & Shu (1988), is developed into solution of N-S equation, and the results are compared with exact solution of Burger equation with viscousity. The result of 2D problem has been also compared with the one obtained by solving Euler equation.

Key words: discontinuous galerkin method, Navier Stokes equation
