At large Mach numbers, the interaction of an oblique shock wave with a turbulent boundary
layer (SWTBLI) developing over a flat plate gives rise to a separation bubble known to
exhibit low-frequency streamwise oscillations around St L= 0. 03 (a Strouhal number based
on the separated region length). Because these oscillations yield wall pressure or load
fluctuations, efforts are made to reduce their amplitude. We perform large eddy simulations
to reproduce the experiments by Wang etal (2012) where a rake of microramp vortex …
