Shock wave laminar boundary layer interaction (SWBLI) over a double wedge at Mach 7.14 and 7.11 were simulated using the commercial ow solver GASPex. An inviscid sim-ulation was performed at Mach 7.14 for validation. Results for the region downstream of the_rst shock wave show less than one percent error in comparison with oblique shock wave theory. Laminar perfect gas simulations were performed for stagnation enthalpies of 2 MJ/kg and 8 MJ/kg. The computed heat transfer distribution agrees closely with the experiment upstream of the shock wave laminar boundary layer interaction; however, signi_cant di_erences are evident in the region of the interaction. In particular, the time-accurate simulations indicate a signi_cantly longer physical time to achieve steady state than observed in the experiment.
