A detailed comparison of experimental and computational results on the flowfield structure of a Mach 4, 15 degree symmetric crossing-shock wave/turbulent boundary layer interaction is presented. Experimentally obtained Planar Laser Scattering images are compared with static pressure contours predicted by the computation, with the computational results showing good overall agreement with the experimental data. The experimental and computational results are used in a complementary manner to develop a detailed flowfield model of the crossing shock interaction. The flowfield structure is found to consist of a complex shock structure overlying a large viscous separated region. This region occupies a significant portion of the outflow duct and consists of an accumulation of low-Mach-number, low-stagnation-pressure fluid. This region may have significant implications for sidewall compression inlets.
