Abstract:

The recent developments of high resolution schemes, especially, high-order and high-robustness shock-capture schemes, and direct numerical simulation (DNS) cases for hypersonic turbulent flows are reviewed in this paper. The numerical methods include the high-resolution shock-capture methods and the technique to stabilize computation for hypersonic flows, as well as, the developments of WENO and monotonicity preserving schemes. The DNS studies include the effects of compressibility, wall temperature and high-temperature real gas on the turbulent flows, and the studies of hypersonic transition flows are also reviewed briefly. Furthermore, an OpenCFD code developed by the author which is compressible and high-resolution, is addressed briefly

Key words: hypersonic, turbulence, direct numerical simulation, high-resolution numerical method, OpenCFD
