Using a confined space to facilitate jetting for fluid-containing biocompatible cavitation nuclei
Résumé
A bubble collapsing near an interface may result in the formation of a liquid jet protruding from the distal bubble side, through the bubble, towards the interface. Ultrasound-assisted jetting has been observed when subjecting fluids to acoustic amplitudes above the inertial cavitation threshold, limiting its application in medicine. The purpose of this study was to investigate the feasibility of low-amplitude jetting for fluid-containing biocompatible cavitation nuclei, by placing the region of interest in a confined space to ensure a standing wave field.
