Cavitation erosion from single acoustically driven bubbles.

ABSTRACT: Acoustic cavitation is achieved by exciting mechanical vibrations at ultrasonic frequencies, which in turn cause the formation of bubble clouds, followed by flows and emulsification. Typically, the effects of acoustic cavitation clouds on cleaning and erosion are difficult to predict or model due to the complex interactions among numerous bubbles. Systematic studies of acoustic cavitation bubbles are simplified by using single cavitation bubbles as a means of controlled cavitation, owing to their precisely defined timing and properties, which can be induced within an acoustic field by seeding a small laser-induced bubble within it. This work presents findings on the erosion of solid surfaces initiated by a single acoustic bubble. Optical seeding of a small cavitation bubble is combined wit
