The turbulence that occurs in the low-pressure region behind a rocket traveling at supersonic speeds is complex and not well understood. In the first experimental study of its kind, researchers at the University of Illinois at Urbana-Champaign helped close the knowledge gap for these flows by proving the existence of hairpin vortices in a supersonic separated flow.
