Turbulence in a Shock-Wave Boundary-Layer Interaction

Direct measurements of the Reynolds normal and shear stresses have been made upstream and downstream of a two-dimensional, adiabatic, shock-wave boundary-layer interaction at M-2.9. The measurements were obtained independently with a laser velocimeter and a constant-temperature, hot-wire anemometer. In addition to these turbulence data, mean velocity data were obtained with the laser velocimeter and compared with data obtained from pitot-static probe. Obtained from the two independent systems, the turbulence data are compared with each other and with previous turbulence measurements. These data are examined in light of modeling the Reynolds stresses appearing in the streamwise momentum equation.
