Highlights

1. Shock/Boundary-Layer Interactions (SBLIs) and their consequences in high-speed aircraft are reviewed.

2. Various active and passive control strategies that have been used to mitigate the effects of SBLI are addressed.

3. The efficacy of Porous Cavity and Micro-Vortex Generators in controlling SBLI is described in detail.

Abstract

The primary focus of the present survey is to categorize the results of various investigations on the Shock/Boundary-Layer Interactions (SBLIs), their repercussions, and the effective ways to control them. The interactions of shock waves with the boundary layer are an important area of research due to their ubiquity in several applications ranging from transonic to hypersonic flows. Therefore, there is a need for a detailed inspection to understand the phenomena to predict its characteristics with certain accuracy. Considering this in mind, this article presents some key features of the physical nature of SBLIs, their consequences, and the control techniques in a sequential manner; in particular, the passive control techniques for the supersonic and hypersonic intakes are reviewed in detail.
