Acoustic Emission by a Vortex Ring Passing near a Sharp Wedge
Chien-Cheng Chang,Tzu Lin Chen +1 more
TL;DR: In this paper, the acoustic field of a vortex ring passing near a sharp wedge of span angle was analyzed at low Mach numbers, and it was shown that the sound pressure at large distances x is proportional to c$^{-\pi /\phi \_{1}}$U$^{\pi / \phi \{1}+2}$L$€(x$-2)$x$ −1}, where x is the shortest distance of the vortex ring from the edge of the sharp wedge.
