Dynamics of Droplet Splashing Induced by Cavitation Bubble Collapse

This chapterDynamics focuses on the dynamic characteristicsCavitation bubble of the dropletDroplet splashing induced by the collapse of the cavitation bubble. Firstly, the effect of the relative position of the cavitation bubble on the splashing behavior of a droplet is observed by the high-speed camera. Secondly, the flow fieldFlow field distribution near the gas–liquid interface is analyzed, including pressure field, velocity field, baroclinityBaroclinity, and vortexVortex distribution. Finally, the critical stability criterion of the interface is further discussed, and the influencing mechanism of cavitation bubbleCavitation bubble collapseCollapse on the dropletDroplet splashing behavior is revealed together with the instantaneous droplet surface breaking.
