Abstract

Sound generated by the pairing of two inviscid finite-core-size two- dimensional vortices is studied numerically using the contour dynamics method and vortex sound theory. Results indicate that the resulting sound field is a lateral quadrupole type and its axis rotates with nonuniform speed about the origin of the source region. Results also show that the accelerating and decelerating motions of the vortices are important in the sound generation.
