Flowfield scaling in sharp fin-induced shock wave/turbulent boundary-layer interaction

This paper presents the results of an experimental investigation of the three-dimensional interaction of a swept planar shock wave with a turbulent boundary layer. The shock wave was generated by a sharp, unswept fin mounted normal to a flat test surface. On the two test surfaces used, the incoming boundary layers varied in thickness by 3:1. In both cases, the freestream Mach number was nominally 3, the freestream Reynolds number 6.3 X 10 m~ *, and the wall temperature close to adiabatic. Detailed yaw angle and pitot pressure surveys in the two cases reveal a similar flowfield structure that can be correlated using a simple scaling technique.
