Shock Wave-Boundary Layer Interaction: A Survey of Recent Development

This paper reviews the latest research advancements in shock wave boundary layer interactions. These interactions are crucial in aerospace engineering, particularly in design of hypersonic vehicle inlets, flow control, and thermal protection systems. The paper first revisits the fundamental physical phenomena and theoretical models of SWBLI, then delves into recent experimental and numerical studies under various flow conditions, including supersonic inlets, turbomachinery, the effects of expansion waves, and the impact of roughness elements. Through an analysis of these research findings, we summarize the main characteristics, influencing factors, and control methods of SWBLI, and highlight future research directions and challenges.
