Numerical solution of compressible flow problems using the finite volume flux-vector splitting schemes on unstructured meshes


Abstract eng:
This paper is focused on the numerical solution of the nonlinear system of the Euler equations, which describe the transonic flow of an inviscid fluid. The computation was performed using the finite volume method defined for unstructured grids. Three explicit flux-vector splitting schemes (Steger-Warming, van Leer, AUSM) are discussed. In order to improve their space accuracy, a linear reconstruction with the Barth’s limiter, which was specially proposed for unstructured grids, is applied. All schemes mentioned here are compared with each other for a selected test case of transonic flow around the NACA 0012 airfoil. Further, this paper describes an algorithm of mesh adaptation for a better capturing of shock waves.
