Low-frequency unsteadiness mechanisms in shock wave/turbulent boundary layer interactions over a backward-facing step

Weibo Hu, Stefan Hickel, Bas W. van Oudheusden

The low-frequency unsteady motions behind a backward-facing step (BFS) in a turbulent flow at $Ma=1.7$ and $R{e}_{\infty }=1.3718\times 10^5$ is investigated using a well-resolved large…
