Abstract
The interaction of two laser-induced cavitation bubbles was investigated experimentally.The dynamics of each individual bubble can be influenced by the oscillation and the shock wave emission of the other bubble. We tried to distinguish between both interaction mechanisms by introducing an interface between the cavitation bubbles that should only allow the shock wave mediated bubble interaction. Our photographs show that bubbles interact even through interfaces; an influence of the shock wave alone on a cavitation bubble, however, was not visible. The dominant interaction mechanism was that of the mutual interaction between two oscillating bubbles (Bjerknes force).KeywordsShock WaveCavitation BubbleBubble DynamicBubble CollapseShock Wave PressureThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
