Analysis of the Large Eddy Simulation of a Shock Wave and Turbulent Boundary Layer Interaction

The large eddy simulation (LES) of a compression ramp shock wave and turbulent boundary layer interaction (STBLI) is presented. The ramp angle is 24◦ and the incoming boundary layer flow conditions are Mach 2.9 and Reθ 2900. The LES data cover approximately 1300 Lsep/U∞ to statistically resolve the aperiodic cycle of the low-frequency unsteadiness that is characteristic of these types of flows. The dynamics of the flow downstream of the shock are characterized using this new numerical data set.
