Acoustic cavitation structures and simulations by a particle model

Cavitation bubbles in acoustic resonators are observed to arrange in branch -like patterns. We give a brief review of the anatomy of such structures an d outline an approach for simulation by individual, moving bubbles. This pa rticle model can reproduce an experimentally observed transition between di fferent structure types in a rectangular resonator cell. (C) 1999 Elsevier Science B.V. All rights reserved.
