Abstract

The acoustic pulse emitted from a bubble detaching from a submerged orifice begins with a rarefaction before the bubble has detached. By implementing an experimental technique where the acoustic pulse measured from a hydrophone was synchronised with the image acquisition from a high-speed camera the behaviour of the bubble surface can be observed during the initial stage of the acoustic emission. The bubble is found to detach slightly before the local minimum pressure measured in the acoustic signal.
