Summary
A TVD-time dependent discretization of the Euler equations is formulated for unstructured grids. The grid is generated by Delaunay triangulation. The spatial discretization is based on the vertex-centred finite volume method with an upwind definition of the fluxes based on polynomial flux-difference splitting. The time dependent system is integrated with the standard Runge-Kutta type multistage time stepping method. Four stages are used with standard time step lengths. Adaptive refinement of the grid is done based on a pressure difference criterion. The method is illustrated on a supersonic wedge flow.
