Numerical simulation and validation of high-speed turbulent and chemically-reacting flows

Mixing and combustion processes in scramjet engines involve complicated aerothermochemical features such as interactions between shock-waves and boundary-layer, shock induced-combustion and recirculation zones. In this study, a numerical solver is developed and validated to be an efficient future...
