Swept Impinging Oblique Shock/Boundary Layer Interactions
November 5, 2021


Renewed interest in high-speed atmospheric flight has brought increased attention to shock/boundary layer interactions (SBLIs). SBLIs are ubiquitous in high-speed aerodynamics and are known to produce significant pressure fluctuations and elevated surface heat flux which can have serious implications on control surfaces, propulsion systems and overall structural integrity. The majority of SBLI basic research has focused on nominally 2D SBLIs, but practical applications require the study of 3D cases. The swept impinging oblique SBLI allows examination of the fundamental influence of sweep without complications associated with redirection by or reattachment to a physical surface but has received surprisingly little attention in the open literature. This talk will review recent efforts on the study of swept impinging oblique SBLIs considering inviscid, mean, and unsteady flow features. The findings are placed in the context of other 3D SBLIs (e.g., swept ramps and fins) where possible and an outlook for future research is provided.
