Abstract
The Euler and Navier-Stokes equations are solved on unstructured triangular grids. The Finite-volume method is used for the discretization on cell-vertex and node-centered arrangements of control volumes. For comparisons the flux-vector splitting concept as well as central formulations of the fluxes are employed. Viscous fluxes are computed in a central way. Mesh generation techniques are briefly discussed. Furthermore three mesh adaptation methods are presented. Simple test cases were chosen to compare the solutions of different methods.
