Comparative study on single-incident and dual-incident shock wave/turbulent boundary layer interactions with identical total deflection angle

Xin Li et al.

Summary: This study investigates the interactions between the boundary layer and two successive incident shock waves in supersonic mixed-compression inlets. Experimental and analytical methods are used to study the turbulent boundary layer separation induced by single and dual shock waves. The study reveals different flow features and separation region shapes depending on the distance between the shock waves.

Flow features of swept shock/turbulent boundary-layer interaction due to a gap beneath a sharp fin

Dustin L. Otten et al.

Summary: This numerical study explored the shock/turbulent boundary-layer interaction generated by a sharp fin with a 60-degree leading-edge sweep mounted above a flat plate at Mach 2.5, finding that the sweep angle and gap between the fin and plate affect incipient separation and interaction strength. Pressure difference across the fin leads to vortex formation on the leeward side, while gaps induce additional vortices.

Tomography-like flow visualization of a hypersonic inward-turning inlet

Yiming Li et al.

Summary: In this study, the flow field in a typical inward-turning inlet was visualized using Planar Laser Scattering method, confirming the presence of Counter-rotating Vortex Pairs (CVPs) and unraveling their generation mechanisms. The V-shaped cowl notch was found to significantly affect downstream flow and should be thoroughly examined in practical applications.
