Characterization of jet parameters related to cavitation bubble dynamics in a vicinity of a flat liquid–liquid interface

Orthaber, Uroš (author), Dular, Matevž (author), Petkovšek, Rok (author)

Presented study analyses different jet parameters that appear during and after bubble collapse, namely bubble center displacement, length of a jet-pierced bubble and size of the rebounded bubble and their relation to anisotropy parameter in a vicinity of a liquid–liquid interface. In experiments cavitation bubble was produced with a focused pulsed laser and its dynamics was recorded by a high-speed camera. Two different types of liquid-liquid interfaces consisting of distilled water and two types of silicone oil were used for the study in order to be able to compare the influence of anisotropy parameter on the magnitude of considered jet parameters. The elongation of the cavitation bubble during jet protrusion was analysed and compared for both interface types. The study exhibits systemic approach to jet parameter consideration and presents an important step in understanding the behaviour of cavitation bubble near liquid-liquid interfaces.
