The mean flowfield of a three-dimensional supersonic turbulent boundary layer, generated by a 20-deg isentropic compression, was studied experimentally and numerically. Experimental data include surface flow visualization, wall static pressures, surface skin friction, and surveys of pitot pressures, yaw angles, and static pressures. Earlier published comparisons with data computed from the three-dimensional Reynolds-averaged compressible Navier-Stokes equations with an algebraic turbulence eddy viscosity closure show good agreement within experimental and computational uncertainties. Focus of the current work is the presentation of different scalings of the experimental data and the proposal of a new model for the mean flowfield scaling. Comparison to a subsonic three-dimensional boundary layer is made for this new scaling law.
