Three-dimensional acoustic scattering by vortical flows. II. Axisymmetric scattering by Hill’s spherical vortex

Abstract

The general theory of Part I is applied to the the specific case of scattering of a wave incident along the axis of Hill’s spherical vortex. The full asymptotic solution to the initial-value problem is calculated. Results agree with the general approach, showing that the conditions required for the latter to hold apply in the case of Hill’s spherical vortex.
