Shock/boundary-layer interaction occurs in many engineering applications. This includes wings of transonic aircraft, turbine blades, supersonic aircraft intakes and rotor tips. In general, interaction of the shock wave system with the boundary layers developing on the wings, intake walls, and so on leads to thickening of the boundary layer and possible separation. This can lead to higher drag in aircraft, wing buffeting, loss of thrust and intake buzz. It is therefore desirable to eliminate or reduce the extent of flow separation.
Control of shock/boundary-layer interaction can be achieved by either controlling the boundary layer upstream of the interaction or the shock system. Examples of strategies to achieve the former include boundary-layer blowing and suction, use of slots and vortex generators, while use of shock control bumps belong to the latter. In the more recent past, flexible surfaces and permeable walls has been used for controlling shock/boundary-layer interactions.
In this Research Topic we would like to focus on some of the recent strategies adopted in control of shock/boundary-layer interaction, while still considering advances in existing methods. Manuscripts submitted can be review articles, full length articles or short communications. Short communications should primarily focus on innovative strategies in this field.
