High
power input of ultrasound to liquids causes acoustic cavitation. In typical
resonator set-ups, the cavitation bubbles form dynamic structures that result
in an inhomogeneous bubble distribution. The pattern formation processes are
still not completely understood, and a detailed observation requires fast
recording facilities. The talk presents recent results from high-speed
recordings of acoustic cavitation bubble structures in different resonator
cells and tries to explain and simulate some of the observed pictures by a
particle approach.
