Transition location effect on oblique shock-wave/boundary-layer interaction at M=1.5

Abstract

The effect of transition location on the interaction between an oblique shock-wave and a boundary-layer at M = 1.5 on a flat plate is investigated via direct numerical simulations. It is shown that the shock trips transition at the impingement location and the effect of the impingement location on the separation is studied for laminar, transitional and turbulent interactions. Qualitative agreement is obtained with the experiments, as part of the European FP7-2012 TFAST project.
