Structure stability of cyclic chain-like cavitation cloud in thin liquid layer

In this paper, the evolution of cavitation bubbles is investigated. A model developed to describe cyclic chain-like cloud and analyze its structure stability in a thin liquid layer. By considering effect secondary acoustic radiation bubbles, dynamic equations three zones chain are obtained. The Bjerknes force selected used explore interaction between different regions. Numerical results show that newborn inside pure zone layer can be attracted by at bubble chain. number density affect coupling strength it closely related driving pressure. Therefore, disrupted perturbations To verify our analysis, we observe strong field using high speed camera. It observed simultaneous collapse local occurs, liquid-like layers distributed randomly. boundary oscillates with field, these sustain about 4 cycles. experimental accord well theoretical results.
