Investigation of interaction effects on dual-frequency driven cavitation dynamics in a two-bubble system

open access: yesUltrasonics Sonochemistry, 2023
The cavitation dynamics of a two-bubble system in viscoelastic media excited by dual-frequency ultrasound is studied numerically with a focus on the effects of inter-bubble interactions.

Multi-bubble scattering acoustic fields in viscoelastic tissues under dual-frequency ultrasound

open access: yesUltrasonics Sonochemistry, 2023
Bubbles are widely used in the medical field due to their strong acoustic scattering properties, and the interaction between bubbles affects the scattering acoustic field caused by the bubble cluster.

A hydrodynamic interaction between bubbles and gas supply system during gas bubble departures in liquids: an experimental study

open access: yesScientific Reports, 2023
In the present paper, the hydrodynamic interactions between bubbles and the gas supply system to a needle were experimentally investigated. In experimental investigations in one of the needles, the air volume flow rate was constant, and in the ...

Dynamics of a vapor nanobubble collapsing near a solid boundary [PDF]

open access: yes, 2015
In the present paper a diffuse interface approach is used to address the collapse of a sub-micron vapor bubble near solid boundaries. This formulation enables an unprecedented description of interfacial flows that naturally takes into account topology ...

A new cavitation model based on bubble-bubble interactions [PDF]

open access: yesPhysics of Fluids, 2018
In this paper, a new model based on bubble-bubble interactions is proposed for cavitation. Unlike the well-known existing models (Rayleigh-Plesset, Gilmore), which are derived from the local balance equations in the vicinity of a single cavitation bubble, the present approach is based on the mutual interaction between two spherical bubbles of different

A new cavitation model considering inter-bubble action

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2021
The process of cavitation involves generation, growth, coalescence, and collapse of small bubbles and is tremendously influenced by bubble–bubble interactions.

The impact of red giant/AGB winds on AGN jet propagation [PDF]

open access: yes, 2017
Dense stellar winds may mass-load the jets of active galactic nuclei, although it is unclear what are the time and spatial scales in which the mixing takes place.

Interaction between double nonspherical bubbles in compressible liquid under the coupling effect of ultrasound and electrostatic field

open access: yesActa Acustica, 2022
A dynamic model for a double-bubble system in compressible liquid under the coupling effect of ultrasound and electrostatic field was developed here. In this study, we mainly discussed the effect of the interaction on the investigated bubble using the ...

Interaction and coalescence of large bubbles rising in a thin gap [PDF]

open access: yes, 2012
We present accurate measurements of the relative motion and deformation of two large bubbles released consecutively in a quiescent liquid confined in a thin-gap cell.

Numerical Study on the Rising Motion of Bubbles near the Wall

open access: yesApplied Sciences, 2021
Based on the volume of fluid method (VOF), the rising characteristics of bubbles in near-wall static water are studied. In this study, the influence of the wall on the rising motion of the bubble was studied by changing the distance of the bubble wall ...
