Equilibrium Calculation of Augmented Shock-Tunnel Heat Flux at High-Pressure and High-Enthalpy Conditions

摘要

RECENTLY, shock-tunnel experiments have been conducted atnhigh-pressure and high-enthalpy conditions such as a reservoirnpressure (P ) of 50 MPa and a reservoir enthalpy (H )of =nin order to study laminar-to-turbulence transition on hypersonicnvehicles [1–3]. In those experiments, unexpected largewall heat fluxnto test models was measured, which was not observed at low-npressure conditions. The cause of the heating augmentation remainsnan open issue.
