- Experimentally validated numerical simulations shed light to the deformation processes of cavitation bubbles under the influence of weak pressure gradients, such as those induced by gravity. It is shown for the first time that the driving force behind focused jetting phenomena is linked with the formation of a positive feedback mechanism amplifying the biased collapse at the bottom side of the bubble. The study let to a successful EU-MSCA network funding currently 15PhD students across Europe and investigating relevant mechanisms and applications on lithotripsy, histotripsy and drug delivery under the influence of focused ultrasounds.
