Abstract
The conditional analysis of the phases in the aperiodic unsteadiness of a shock wave and turbulent boundary layer interaction is presented. The low-cost of large eddy simulations as compared to direct numerical simulations allows for increased simulation length, enabling the convergence of conditional statistics of the aperiodic cycle characteristic of shock wave and turbulent boundary layer interactions. The time-resolved large eddy simulation data of a Mach 2.9, 24◦ compression ramp is conditionally averaged over the phases of the aperiodic cycle showing distinct flow structures as seen in the conditionally sampled flow fields from experiments and numerical simulations of similar configuration.
