Abstract

Heat flux measurements of transitional shock-wave/boundary-layer interactions (SWBLI) were conducted by quantitative infrared thermography. The shock intensity and mutual position of the impingement and transition locations were varied independently. The shock induced Stanton number peaks are maximal for transitional SWBLI and stronger shocks cause higher heat transfer amplification. The highest amplification rates for each shock intensity depend on the transitional state at the impingement location. Weaker shocks require a further developed transitional state at the impingement location for the highest amplification due to less shock induced turbulence. Numerical simulations with the DLR TAU-Code were conducted for the limiting boundary layer cases (laminar & turbulent) and cover the entire experimental parameter study.
