Abstract

The article reviews main ingredients for a bottom-up approach to understand and model acoustic cavitation structures.
Based upon the dynamics of a single, spherical bubble in a sound field, the fate of a bubble in a given
acoustic set-up and collective behavior in multibubble systems are derived. The discussion includes nucleation and
oscillation of bubbles, their shape stability, and rectified gas diffusion. Furthermore, acoustic forces on pulsating
bubbles and bubble translation are addressed. The different aspects are combined in bubble life cycle diagrams, and a
particle model for the description of many interacting bubbles is proposed. The application of this method for
numerical simulation of experimentally observed acoustic cavitation structures is demonstrated in examples.
