Bubble dynamics in boiling histotripsy [PDF]
Ultrasound in Medicine & Biology, 2018 Boiling histotripsy is a non-invasive, cavitation-based ultrasonic technique which uses a number of millisecond pulses to mechanically fractionate tissue. Though a number of studies have demonstrated the efficacy of boiling histotripsy for fractionation of solid tumours, treatment monitoring by cavitation measurement is not well studied because of the ...

Coupling bubble and material dynamics to model cavitation peening and pitting
Journal of Fluid Science and Technology, 2016 The effects of cavitation bubble dynamics on material peening and pitting is investigated numerically using a coupled fluid and material dynamics approach. The model is applied here to the study of peening and pitting of metallic materials resulting from

Controlled Cavitation in Microfluidic Systems [PDF]
, 2007 We report on cavitation in confined microscopic environments which are commonly called microfluidic or lab-on-a-chip systems. The cavitation bubble is created by focusing a pulsed laser into these structures filled with a light-absorbing liquid.

Bubble Dynamics in Laser Lithotripsy [PDF]
Journal of Physics: Conference Series, 2015 Laser lithotripsy is a medical procedure for fragmentation of urinary stones with a fiber guided laser pulse of several hundred microseconds long. Using high-speed photography, we present an in-vitro study of bubble dynamics and stone motion induced by Ho:YAG laser lithotripsy.

Shock Wave Emissions of a Sonoluminescing Bubble
, 1998 A single bubble in water is excited by a standing ultrasound wave. At high intensity the bubble starts to emit light. Together with the emitted light pulse, a shock wave is generated in the liquid at collapse time.

Numerical bubble dynamics [PDF]
, 2003 Abstract A computational study of the dynamics of a gas bubble rising in a viscous liquid is presented. The proposed numerical method allows to simulate a wide range of flow regimes, accurately capturing the shape of the deforming interface of the bubble and the surface tension effect, while maintaining a good mass conservation.
