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 ...

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.

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 ...

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 ...

Multibubble Sonoluminescence from a Theoretical Perspective

open access: yesMolecules, 2021
In the present review, complexity in multibubble sonoluminescence (MBSL) is discussed. At relatively low ultrasonic frequency, a cavitation bubble is filled mostly with water vapor at relatively high acoustic amplitude which results in OH-line emission ...

Three-dimensional shock-sulfur hexafluoride bubble interaction

open access: yesAIP Advances, 2019
The evolution of shock-sulfur hexafluoride (SF6) bubble interaction is investigated using a detailed three-dimensional numerical simulation. The influences of the end wall distance on the bubble evolution are analyzed by using the high-resolution ...

Analysis of energy conversion and mass damping of synchronized and same-size multibubble [PDF]

open access: yesInternational Journal of Fluid Engineering
Multibubble formation is a common phenomenon. In this paper, a model of a multibubble accounting for heat transfer, phase change, and bubble–bubble interaction through bubble-induced pressure waves is proposed.

Morphological Analysis of a Collapsing Cavitation Bubble near a Solid Wall with Complex Geometry

open access: yesApplied Sciences, 2023
The interaction mechanism between the cavitation bubble and a solid wall is a basic problem in bubble collapse prevention and application. In particular, when bubble collapse occurs near solid walls with arbitrarily complex geometries, it is difficult to
