THE DEAERATION OF WATER BY A SOUND BEAM

Abstract

A calculation is made to determine the diffusion of air into bubbles as a result of mechanical motions induced by a sound beam. The case of an isolated bubble in a weak sound beam of wave length considerably greater than the bubble radius is considered. The effects of surface tension, viscosity, and energy dissipation are neglected. The diffusion problem is treated by means of a perturbation technique. The growth of the bubble is of second order in the sound pressure (proportional to the sound intensity). The effect is shown to be sufficient to account for a significant bubble growth, especially for very small bubbles.
