Curved shock wave interaction with a spiral vortex
Nearly all experimental and numerical studies of shock wave/vortex interactions have shown that the vortex largely maintains its integrity after shock transit, even though it can become elongated or is raised to a higher pressure. Some studies with curved shock waves and with multiple wave traverses have, however, shown evidence of vortex breakup. The mechanisms for this are not yet understood. This paper explicitly explores the influence of incident shock curvature and approach direction on the interaction process with a spiral vortex.
