Investigation of 3D Shock-Boundary Layer Interaction: A Combined Approach using Experiments, Numerical Simulations and Stability Analysis

Abstract

Due to the renewed interest in sustained high-speed atmospheric flight, shockwave boundary-layer interaction is again receiving considerable attention. The incomplete understanding of the underlying physical mechanisms for both 2D and 3D SBLI poses a roadblock for the reliable and efficient operation of high-speed flight vehicles. A combined research approach, encompassing spatially and temporally resolved measurements, highly accurate numerical simulations as well as local and global stability analyses, has been executed for investigating three-dimensional SBLI. The 3D SBLI are generated by an impinging oblique shock wave that is swept back with respect to the mean flow primarily at Mach 2.3.
