Modeling of shock boundary layer interactions and stability analysis using particle approaches
Hypersonic flow separation and laminar shock wave boundary layer interactions (SWBLIs) have received considerable attention since these interactions can lead to laminar to turbulent transition, unsteadiness, and localized high pressure and heating regions. Accurate predictions of these phenomena, …

Design and development of a rectangular supersonic wind tunnel facility for the study of shock/boundary layer interactions
… to evaluate simple, passive, and bleedless inlet shock wave/boundary layer interaction control options, called micro-vortex generators. A new supersonic wind tunnel was designed and built on the University of Illinois campus to enhance high-speed flow testing capabilities used for studying these …

Experimental and numerical investigations of the off-design flow physics in a supersonic through-flow fan cascade
… found to be strongly influenced. by upstream shock-boundary-layer-interactions, the strength of which varied with cascade incidence. In contrast, the peak levels of turbulence properties within the shear layer were found to be largely independent of cascade incidence, and could be …

Heat Transfer and Flow Characteristics on the Rotor Tip and Endwall Platform Regions in a Transonic Turbine Cascade
… in regions with local flow reattachment and new-boundary layer formation. Conversely, the lowest heat transfer occurs in regions with boundary layer thickening and separation/lift-off flow. However, boundary layer separation results in additional secondary flow vortices, such as the squealer …

Experimental and Numerical Investigations of Optimized High-Turning Supercritical Compressor Blades
… revealed the loss reduction mechanism: severe boundary layer separation occurred on the suction surface of the baseline blade while no separation occurred for the optimized blades. Furthermore, whether the boundary layer was separated or not was found due to different shock patterns, different …

Fluid-structure interaction of a cantilevered plate in supersonic separated flow
… on the cantilevered plate in the absence of shock-boundary layer interactions that would be present if the plate were inclined to the flow. The height of the cavity has been chosen such that it corresponds to the height of a flap of equal length deflected at 20 degrees. Both rigid and …

Supersonic Corner Flows in Rectangular Channels
… such as in wind tunnels and in aircraft inlets. Shock-boundary-layer interactions in these flows are known to exhibit significant three-dimensionality, due to the presence of sidewalls and associated corner boundary layers. The main effect is on the local separation of these corner regions, which …

The role of aerothermochemistry in double cone and double wedge flows
… iv) to extend the experimental database for shock wave boundary/layer interactions. An expansion tube is used to generate flows with enthalpies ranging from 2.2-8.0 MJ/kg (2-4 km/s) and Mach numbers from 4-7. The expansion tube is a novel impulse facility for accelerating a test gas to these …
