Abstract

Abstract:

The progress of numerical simulations capability, which is related to fidelity, accuracy and efficiency, for prediction of hypersonic flow during the last several decades are reviewed. For physical modeling, the current status of modeling and simulation about high-temperature gas effects, rarefied gas effects and turbulence effects in hypersonic flow simulations is reviewed. And great emphasis is placed on hypersonic boundary layer transition modeling based on Reynolds-averaged Navier-Stokes (RANS) equations. For spatial discretization schemes, a review of development and application for usual 2nd order upwind schemes and high-order schemes are given. For time marching schemes, development and application for implicit time marching schemes is briefly summarized. For uncertainty quantification, a review of its concept, source and analysis method is firstly addressed, and then the primitive results of iterative error estimation, spatial discretization error analyses using Richardson extrapolation and uncertainty quantification using sensitivity derivatives are also presented. At last, some possible future directions on numerical simulations for hypersonic flow are discussed.

Key words: hypersonic flow, numerical simulation, physical modeling, numerical method, error, uncertainty
