In this paper, we present the Lax-Wendroff theorem of entropy dissipation method for scalar conservationbr /laws in one space dimension. Suppose that ul(x, t) the numerical solution computed by the entropy dissipationbr /method converges to a function u(x, t) as l ? ?,then u(x, t) ...

一维激波管问题——计算流体力学(Lax-Wendroff格式) 本文用python3.6对一维激波管lax激波管问题进行了计算,使用了Lax-Wendoff格式,激波管问题的初值采用了lax激波管的初值(具体见代码),推进时间为0.14s,网格数为500,相较于Lax-Friedrichs格式在稀疏波与激波处更加符合解析解, 接触间断面处会发生耗散。
Lax showed that, in a wide class of cases, methods of numerical analysis give accurate solutions to the equations, and, in work with others (including the German-born American mathematician Kurt Friedrichs and American mathematician Burton Wendroff), he introduced new numerical methods for finding ...

The classical Lax-Wendroff theorem ensures that conservative and consistent schemes cannot suffer from this pathology: whenever they converge, the limit must be a weak solution. If, in addition, the scheme satisfies a discrete entropy inequality, then the limit must be an entropy solution. Entropy...
The article focuses on the application of a Lax-Wendroff type theorem for unstructured quasi-uniform grids. It says that based on the theorem, the limit is a frail solution of the system if the progression of estimated solutions to a system of hyperbolic conservation laws produced by a ...
We prove in this paper the Lax–Wendroff consistency of a general finite volume convection operator acting on discrete functions which are possibly not piecewise-constant over the cells of the mesh and over the time steps. It yields an extension of the Lax–Wendroff theorem for general colocated...
