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.
        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.
