Acoustic cavitation structures and simulations by a particle model

Ultrason Sonochem. 1999 Mar;6(1-2):25-9. doi: 10.1016/s1350-4177(98)00025-x.


Cavitation bubbles in acoustic resonators are observed to arrange in branch-like patterns. We give a brief review of the anatomy of such structures and outline an approach for simulation by individual, moving bubbles. This particle model can reproduce an experimentally observed transition between different structure types in a rectangular resonator cell.
