Abstract

Recent progress in flux vector splitting is reviewed with the aim to obtain high resolution and robustness for hypersonic reacting flow simulations. The numerical behaviour of promising AUSM and CUSP discretization variants is reported and compared. these schemes can be combined with explicit multistage time stepping and multigrid. Large chemical source terms introduce stiffness into the system of equations which is removed by point implicit treatment. the present results demonstrate that efficient 3D simulations of viscous reacting flows with large contrast generated by strong shocks are now feasible.
