Special Course on Shock-Wave/Boundary-Layer Interactions in Supersonic and Hypersonic Flows (Interactions entre Ondes de Choc et Couches Limites dans les Ecoulements Supersoniques et Hpersoniques).
Abstract
Shock-wave/boundary-layer interactions continue to be ubiquitous phenomena in supersonic and hypersonic aerodynamics, and their importance is often critical as, for example, for hypersonic controls and for air intakes in general. This is the reason for the continuous research efforts in this field, aiming at developing reliable methodologies for future vehicle design. Results from these programmes have been reported. The present course reviews the recent progress in this field. In particular, a large part of the course is devoted to swept interactions, both laminar and turbulent, including a discussion of the following topics: (1) The flowfield structure; (2) The scaling and similarity laws; (3) The effect of shock strength on flow features; (4) The effect of shock generator geometry for a given shock strength; (5) Experimental techniques, in particular optical techniques, for the investigation of swept interactions; and (6) Contributions of numerical simulations to the understanding of swept interactions. A limiting factor in the understanding and ability to predict shock wave/boundary-layer interactions is a good knowledge of turbulence behavior. A lecture is devoted specifically to hypersonic interactions.
