摘要: 为将已有的一维守恒律方程满足多个守恒律的Godunov型格式推广到高维守恒律方程中,对二维的线性传输方程设计了一个满足3个守恒律的Godunov型格式.数值试验表明,该格式具有长时间的保结构性. 

关键词: 二维线性传输方程; 守恒律; Godunov型格式 

Abstract:  In order to apply Godunov type scheme satisfying several conservation laws for one dimensional hyperbolic conservation laws to multi-dimensional hyperbolic conservation laws, this paper designs a Godunov type scheme satisfying three conservation laws for two dimensional linear advection equation. The numerical experiments show that this scheme has good structure preserving property in long time numerical simulations.  

Key words: two dimensional linear advection equation, conservation laws, Godunov type scheme
