Simplified second-order godunov-type methods
WebbAbstract This paper presents a second-order accurate adaptive Godunov method for two-dimensional (2D) compressible multicomponent flows, which is an extension of the pre-vious adaptive moving mesh method of Tang et al. (SIAM J. Numer. Anal. 41:487–515, 2003) to unstructured triangular meshes in place of the structured quadrangular meshes.

WebbIn numerical analysis and computational fluid dynamics, Godunov's scheme is a conservative numerical scheme, suggested by S. K. Godunov in 1959, for solving partial differential equations.One can think of this method as a conservative finite-volume method which solves exact, or approximate Riemann problems at each inter-cell boundary.

In the general Godunov-type method, the projection is onto a piecewise polyno-mial function. To determine the properties of these schemes it is necessary to study the properties of the projection operator. We limit our attention to second order Godunov-type schemes based on the Minmod limiter. Namely, the piecewise linear projection in
