Abstract

A slowly forming underwater gas bubble will grow, form a neck and detach when the neck collapses, emitting a pulse of sound. During the late stage of the neck collapse the acoustic pulse displays a rarefaction and the acoustic compression begins shortly after detachment. This compression appears to coincide with the formation of an internal jet inside the bubble and an understanding of the behaviour of the bubble internal jet is sought in order to understand the origin of the acoustic emission. In this study time resolved high speed imaging of the bubble detachment process has been undertaken using planar laser induced fluorescence (PLIF) illumination. From these images the internal jet development and evolution are investigated as well as the effect of the jet on the instantaneous bubble volume. The link between the internal jet and the surface waves on the bubble is also investigated for insight on their contribution to bubble sound emission.
