Evolution behavior of cavitation bubble in pure Sn liquid medium with narrow gap under low-amplitude ultrasound

“…Yu et al [3] , [14] studied the action mechanism of ultrasonic power and liquid medium surface tension on the shape variations of cavitation bubbles near the wall by simultaneous high-speed microscopic imaging method. Xu et al [5] , [15] observed the cavitation behavior at the interface of a pure Sn thin liquid layer. They found the cavitation effect could improve the wettability of the substrate metal surface, and the cavitation effect strengthened with decreasing gap layer.…”
