Shock wave laminar boundary layer interaction over a double wedge in a high mach number flow

Shock wave laminar boundary layer interaction (SWBLI) over a double wedge was simulated at Mach 7.11 with stagnation enthalpy of 2 MJ/kg (low enthalpy case), and at Mach 7.14 with stagnation enthalpy of 8 MJ/kg (high enthalpy case) using the commercial flow solver GASPex. An inviscid simulation was performed at Mach 7.14 for validation and solution justification. In the inviscid case, the region downstream of the first shock wave shows less than one percent difference for any flow parameter in comparison with oblique shock wave theory. In both cases, the flow is assumed to be laminar. The computed heat transfer distribution agrees closely with the experiment at the time reported by experiment where the flow reaches steady state; however, significant difference are evident in the duration in which the flow reaches steady state in the computation. In particular, the time-accurate simulations indicate a significantly longer physical time to achieve steady state than observed in the experiment.M.S.Includes bibliographical referencesby Mohammad Ali Bad
