Experimental study on damage mechanism of blood vessel by cavitation bubbles
Ultrasonics Sonochemistry, 2023 Ultrasound-induced cavitation in blood vessels is a common scenario in medical procedures. This paper focuses on understanding the mechanism of microscopic damage to vessel walls caused by the evolution of cavitation bubbles within the vessels.

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.

On the gas pressure inside cavitation bubbles
Physics of Fluids, 2023 The validity of the reduced order [Delale and Pasinlioglu, “Acoustic cavitation model based on a novel reduced order gas pressure law,” AIP Adv. 11, 115309 (2021)] and of classical polytropic gas pressure laws during the response of a bubble to variations in the pressure of the surrounding liquid is investigated.

Numerical modelling of acoustic cavitation threshold in water with non-condensable bubble nuclei
Ultrasonics Sonochemistry, 2022 Numerical modelling of acoustic cavitation threshold in water is presented taking into account non-condensable bubble nuclei, which are composed of water vapor and non-condensable air.

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

Cavitation in linear bubbles [PDF]
Journal of Fluid Mechanics, 2009 Recent work has developed a beautiful model system for studying the energy focusing and heating power of collapsing bubbles. The bubble is effectively one-dimensional and the collapse and heating can be quantitatively measured. Thermal effects are shown to play an essential role in the time-dependent dynamics.
