Abstract

Shockwave/boundary layer interactions with an impinging oblique shock and turbulent incoming boundary layer on a heatable flat plate were investigated in the High Enthalpy Shock Tunnel Gottingen at a nominal Mach number of 7.4 ¨ and stagnation enthalpy of 3.14 MJ/kg. Wall-to-freestream temperature ratios were set independently of freestream conditions. Schlieren images showed a general increase in the extent of the interaction region for higher wall-to-freestream temperature ratios. Surface heat flux measurements showed that the relaxation of the boundary layer was delayed for higher wall-to-freestream temperature ratios. Pressure relaxation, however, occurred at a similar rate with distance independent of wall-to-freestream temperature ratios. Comparison of maximum surface heating and pressure loads is also undertaken in the central and spanwise locations. Consolidation of the current results is planned to assist numerical rebuilding of these test cases.
