LAUSR

A large database of shock/turbulent boundary layer interactions is compiled to study the separation length scaling over the range of flow conditions including hypersonic interactions. Experimental and computational data of two-dimensional and axisymmetric geometries are included with Mach number from 2 to 10 and ratio of wall to adiabatic recovery temperature from 0.3 to 1.9. A new scaling shows weak interactions collapse by the upstream boundary layer properties, strong interactions do not, and strong separation cases depend on the structure of the downstream flow.
