Abstract

In this paper, a hybrid numerical flux scheme of low diffusion ECUSP (LDE) and HLL scheme is proposed by decomposing the cell-face normal vector. In the direction normal to shocks, the HLL scheme is applied to suppress carbuncles, in the other direction, the ECUSP scheme is implemented to keep low numerical diffusion. The new scheme with fifth-order WENO reconstruction is tested by using several benchmark cases, and then is applied to simulate a three dimensional double cone hypersonic flow of Mach number 12.43. The numerical simulation results agree very well with experiments.
