Evolution behavior of cavitation bubble in pure Sn liquid medium with narrow gap under low-amplitude ultrasound [PDF]

open access: yesUltrasonics Sonochemistry, 2023
In this study, a numerical model of cavitation bubble in the narrow-gap pure Sn liquid medium was established by two-dimensional compressible multiphase flow simulation.

Surface tension of cavitation bubbles

open access: yesProceedings 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.

Effects of medium viscoelasticity on bubble collapse strength of interacting polydisperse bubbles

open access: yesUltrasonics Sonochemistry, 2023
Due to its physical and/or chemical effects, acoustic cavitation plays a crucial role in various emerging applications ranging from advanced materials to biomedicine. The cavitation bubbles usually undergo oscillatory dynamics and violent collapse within

Homogeneous Bubble Nucleation driven by local hot spots: a Molecular Dynamics Study [PDF]

open access: yes, 2009
We report a Molecular Dynamics study of homogenous bubble nucleation in a Lennard-Jones fluid. The rate of bubble nucleation is estimated using forward-flux sampling (FFS).

Experimental study on damage mechanism of blood vessel by cavitation bubbles

open access: yesUltrasonics 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.

Numerical modelling of acoustic cavitation threshold in water with non-condensable bubble nuclei

open access: yesUltrasonics 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.

On the gas pressure inside cavitation bubbles

open access: yesPhysics 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.

Dynamic behavior of the cavitation bubbles collapsing between a rigid wall and an elastic wall

open access: yesAIP Advances, 2021
There are various bubble cavitation phenomena in daily production and life, and near-wall cavitation is the most common one. This paper studies the bubble cavitation dynamics between a rigid wall and an elastic wall, and by changing the distance between ...
