New LES of a Hypersonic Shock/Turbulent Boundary Layer Interaction

In this paper is presented new Large Eddy Simulation data of a hypersonic shock/turbulent boundary layer interaction that is separated in the mean. The incoming flow is a Mach 9.6 turbulent boundary layer at friction Reynolds number Reτ = 450 and the shock is generated by a 34o compression ramp. The duration of the simulation is sufficient to converge the mean flow. The analysis documented in this paper include a basic statistical description of the mean flow and a qualitative assessment of the low-frequency unsteadiness of the shock.
