Sonoporation from Jetting Cavitation Bubbles [PDF]
Biophysical Journal, 2006 The fluid dynamic interaction of cavitation bubbles with adherent cells on a substrate is experimentally investigated. We find that the nonspherical collapse of bubbles near to the boundary is responsible for cell detachment. High-speed photography reveals that a wall bounded flow leads to the detachment of cells. Cells at the edge of the circular area

Surface tension of cavitation bubbles
Proceedings of the National Academy of Sciences, 2023 We have studied homogeneous cavitation in liquid nitrogen and normal liquid helium. We monitor the fluid content in a large number of independent mesopores with an ink-bottle shape, either when the fluid in the pores is quenched to a constant pressure or submitted to a pressure decreasing at a controlled rate.

Impact-driven cavitation bubble dynamics
Experiments in Fluids, 2022 Abstract The dynamics of a single cavitation bubble exposed to a transient acceleration is studied experimentally. A single cavitation bubble is seeded with a pulsed laser in a free-falling and impacting water-filled test tube. After impact, a pressure wave containing compression and rarefaction phases is generated and interacts with ...

Nonspherical laser-induced cavitation bubbles [PDF]
Physical Review E, 2010 The generation of arbitrarily shaped nonspherical laser-induced cavitation bubbles is demonstrated with a optical technique. The nonspherical bubbles are formed using laser intensity patterns shaped by a spatial light modulator using linear absorption inside a liquid gap with a thickness of 40 microm.

Ultrasonics Sonochemistry, 1997 The dynamics of cavitation bubbles on water is investigated for bubbles produced optically and acoustically. Single bubble dynamics is studied with laser produced bubbles and high speed photography with framing rates up to 20.8 million frames per second. Examples for jet formation and shock wave emission are given.

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.

Cavitation And Bubble Dynamics [PDF]
, 1995 Abstract The book describes and explains the fundamental physical processes involved in bubbly dynamics and the phenomenon of cavitation. The study of cavitation and bubbly flow applies to many areas of interest; from valve damage in hydroelectric equipment, ship propellors and internal combustion engines to the performance of ...

Non-spherical collapse of an air bubble subjected to a lithotripter pulse [PDF]
, 2008 In order to better understand the contribution of bubble collapse to stone comminution in shockwave lithotripsy, the shockinduced and Rayleigh collapse of a spherical air bubble is investigated using numerical simulations, and the free-field collapse ...

Mechanics of collapsing cavitation bubbles [PDF]
Ultrasonics Sonochemistry, 2016 A brief survey is given of the dynamical phenomena accompanying the collapse of cavitation bubbles. The discussion includes shock waves, microjets and the various ways in which collapsing bubbles produce damage.
