Validation of High-Speed Turbulent Boundary Layer and Shock-Boundary Layer Interaction Computations with the OVERFLOW Code
... The flat plate test cases use simple single-zone grids that do not model the radius of the plate leading edge, and the viscous wall extends all the way to the inflow plane. The compression ramp cases use a system similar ...

Computational characterization of shock wave - boundary layer Interactions on flat plates and compression ramps in laminar, hypersonic flow
... The number of faces per cell must be considered for two reasons. The first is that an element with more faces will require more computational time, and therefore will run slower than an element with less faces on a ...

Experimental and computational investigation of flow about low aspect ratio ellipsoids at transcritical Reynolds numbers
... Hot films may be placed on the model surface [17], or pressure sensors may be placed flush with the surface or behind pinhole tappings, in order to measure the fluctuations due to turbu- lence [81]. These two methods ...
