GEORGE EMANUEL, in Handbook of Shock Waves, 2001 3.1.4.3 BOUNDARY-LAYER INTERACTION The most important interaction process for a shock is with a boundary layer. If boundary-layer separation occurs, the structure of the flow field can be quite different from what it would be if separation did ...
The effect of boundary layer on the separation distance in a magnetically driven shock tubeRisø-R-321, Risø-321, Risø report 321C.T. Chang
Shock wave boundary layer interactions (SBLIs) are important physical phenomena in a variety of applications in supersonic and hypersonic transport. They are associated with shock wave unsteadiness, increased drag and heating, and shock induced boundary layer separation, all of which can have drastic...

Experiments were conducted in laminar, transitional, and turbulent flows in flow separation regions. The interaction of viscous and nearly inviscid flows is quite common. This phenomenon occurs in flow past a concave corner, when a compression shock impinges on a boundary layer, and in many other...
Separation of a three-dimensional boundary layer An analysis is made of various cases of separation on the surface of a yawed cylinder and on the surface of sharp cones at an angle of attack in a supersonic stream. The position of the lines of separation is determined ... VS Avduevskii...
The flow structure behind the separation point of a laminar boundary layer in a supersonic stream has been investigated. Analytic and numerical solutions are obtained for simple semiinfinite separation zones starting from the leading edge or a point on the smooth surface. The question of the ...

Three dimple patterns were investigated to ascertain their relative effectiveness on controlling boundary layer separation from a low-pressure turbine blade. The three cases included a single row of dimples at 65% of the axial chord with 2.22 cm spacing, a single row of dimples at 65% of the ...
