摘要
本文是论文[1][2]的继续.在本文中,提出了用拟特征线方法解一维守恒的双曲型方程组的间断解问题,并且提出了几种有效的拟特征线格式.特别以激波管问题和溃埧问题为例,作了数值模拟试验,结果表明与准确解是比较吻合的.
This paper is the continuation of the papers.In the paper,thequasi-characteristics method(QCM)is used for solving discontinuous solu-tion of one dimensional hyperbolic conservation laws,and several effectiveQCM-schemes are proposed.Particularly,it is shown how to use the QCMto solve shock tube and dam-failure problems.The numerical results aresatisfactory compared with the exact solutions.
