Reflection and penetration of a shock wave interacting with a starting vortex

Abstract

Experimental and numerical studies are conducted to investigate the interaction of a weak shock wave (M-s = 1.22) and a strong vortex (M-v,M-max > 1). In terms of shock dynamics, two meaningful physics are observed from the experiment: reflected wave from the vortex edge and transmitted wave penetrating the vortex core. These weak waves are shown in the numerical interpretation to contribute to the emission of acoustic waves in shock-vortex interaction.
