Abstract

A new efficient upwind scheme based on the concept of convective upwind and split pressure (CUSP) is developed. The upwinding of the convective term and the pressure split are consistent with their characteristic directions. The scheme has low diffusion to accurately resolve wall boundary layers, and are able to capture crisp shock waves and exact contact discontinuities. The accuracy of the scheme is compared with other popularly used schemes including Roe scheme, Liou's AUSM + scheme, Van Leer scheme, and Van Leer-Hänel scheme. The scheme is tested for the ID Sod shock tube problem, 1D slowly moving contact surface, supersonic flat plate laminar boundary layer, a transonic nozzle with oblique shock waves and reflections that do not align with the mesh lines, and a transonic inlet diffuser with shock wave/turbulent boundary layer interaction. The test cases show that the new scheme is accurate, robust and efficient.
