Aerodynamic Heating in Three-Dimensional Bow Shock Wave/Turbulent Boundary Layer Interaction Region
Aerodynamic heating phenomena in the shock wave/turbulent boundary layer interaction region are one of the most important research tasks and this subject demands further investigation. To explain these phenomena, we investigate the bow shock wave/turbulent boundary layer interaction region induced by a blunt body, that is to say, the model case of the internal flow between a main rocket body and an auxiliary rocket booster. In this study, selecting as the main parameter the distance from the flat plate to the blunt body, the effect of the height is investigated by use of oil flow technique, surface pressure measurements and surface heat flux measurements. The results show that the distance has a major impact on the interaction region. Moreover, this parameter influences the flow behaviour.
