Superpositions of sound time-harmonic plane waves in an ideal liquid, defined by the spherical harmonics, are considered. By way of illustration we present unique families of orthonormal sound beams and localized fields. The obtained solutions describe fields having a very small (about several wavelengths) and clearly defined core region with maximum intensity of field oscillations. It is shown that, as in the case of localized fields in an elastic solid, there exist three families of localized sound fields in an ideal liquid (sound storms, whirls and tornadoes). The main types of the sound fields presented are illustrated by calculating fields, energy densities and energy fluxes. |
