Abstract

The energy relaxation method with Harten-Laxvan-Leer contact (HLLC) flux splitting was implemented for three-dimensional real-gas flow analysis over a reentry space capsule. In the energy relaxation method, the nonlinear pressure law was split into linear and nonlinear parts. The computed pressure was compared with wind-tunnel test data for Mach number 5 and with air curve-fit data for Mach number 10. It was found that energy relaxation method with HLLC flux splitting is an efficient and accurate approach in computing real-gas flows for industrial applications.
