This video shows, for the first time, the temporally and spatially resolved inviscid centrifugal instability in a shock-induced separated flow.  The unveiling of this centrifugal instability is a significant step toward the realization of sustained scramjet powered flight.  The databased used in this video is of a Mach 7 turbulent boundary layer flow over a 33-degree compression corner, and is computed using the large eddy simulation CRoCCo code.
