Vapor bubbles in flow and acoustic fields

Abstract

A review of several aspects of the interaction of bubbles with acoustic and flow fields is presented. The focus of the paper is on bubbles in hot liquids, in which the bubble contains mostly vapor, with little or no permanent gas. The topics covered include the effect of translation on condensation in a subcooled liquid, the action of pressure gradients on bubbles convected by a liquid flow, rectified heat diffusion on stationary and moving bubbles, the effect of permanent gas on this phenomenon, and the action of pressure-radiation (or Bjerknes) forces.
