Shock wave-boundary-layer interactions / edited by Holger Babinsky, John K. Harvey Date : 2011 Editeur / Publisher : Cambridge : Cambridge University Press , 2011 Industrial issues: shockwave boundary layer interaction is a classical phenomenon in all high speed flow and strongly determine the aerothermodynamic performances. In Aeronautics area: Supersonic air-inlet (pumping phenomenon). Transonic profil (buffet phenomenon). Scientific issues: Shock wave / boundary layer interaction is actually Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the ...

Shock-wave/boundary-layer interactions (SWBLI) are of great importance in supersonic transport vehicles. The shock-induced separation and its unsteadiness may lead to harmful influences on the aerodynamic performance and fatigue life of supersonic air-intakes, turbo-machine cascades and supersonic nozzles. We particularly focus on a three-dimensional SWBLI in supersonic flow past a finite-span ... The shock-wave/boundary-layer interactions (SWBLIs) at compression ramps (ramp angle α = 20 - 30 deg) are studied at M a = 2.0 and under two Reynolds numbers (Re 1 = 18,600 and Re 2 = 35,600, with the Reynolds number Re based on boundary-layer thickness). High-speed schlieren operating at 20 kHz are used as the flow diagnostics. Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines.
