Investigation of shock patterns around a double-wedge for hypersonic flows in thermochemical non-equilibrium
Investigation of shock patterns around a double-wedge for hypersonic flows in thermochemical non-equilibrium
Numerical simulations of hypersonic viscous flow in thermochemical non-equilibrium over a double wedge with high Mach and high enthalpy inflow conditions are performed to investigate shock pattern transition. First, simulations for varying second wedge angle are conducted in order to classify the shock patterns. Then, the effects of the thermochemistry on shock pattern transition are investigated by comparing simulations with air, nitrogen and an ideal gas flow. The highlighted effects of the second wedge angle, time and thermochemistry modelling on pattern transition are supported by a shock polar analysis. Finally, quantitative transition criteria are provided to summarise the influence of these three parameters.

Abstract
Numerical simulations of hypersonic viscous flow in thermochemical non-equilibrium over a double wedge with high Mach and high enthalpy inflow conditions are performed to investigate shock pattern transition. First, simulations for varying second wedge angle are conducted in order to classify the shock patterns. Then, the effects of the thermochemistry on shock pattern transition are investigated by comparing simulations with air, nitrogen and an ideal gas flow. The highlighted effects of the second wedge angle, time and thermochemistry modelling on pattern transition are supported by a shock polar analysis. Finally, quantitative transition criteria are provided to summarise the influence of these three parameters.
