Ball motion and bubble ripples in the interaction of cavitation bubble-elastic ball-curved wall [PDF]

open access: yesUltrasonics Sonochemistry
Elastic ball motion and cavitation bubble ripples in cavitation bubble-elastic ball-curved wall interaction was investigated experimentally using single-electrode periodic discharge bubble generation technology and high-speed photography.

Radial oscillation of an encapsulated bubble near a planar rigid wall under dual-frequency acoustic excitation in viscoelastic fluids [PDF]

open access: yesUltrasonics Sonochemistry
Microbubbles play an important role in acoustic cavitation, power ultrasonics, and biomedical diagnosis and therapy. However, the influence of surrounding boundary conditions on the dynamic behaviors of an encapsulated bubble requires more in depth ...

Theoretical Modeling of Bubbling Regimes in Bubble Formation with Bubble-Bubble and Bubble-Wall Interactions

open access: yesJournal of Chemical Engineering of Japan, 2008
In this study, a theoretical model for prediction of bubbling regimes in bubble formation from a single submerged orifice has been developed. The model takes into account both chamber pressure fluctuations, and bubble–bubble and bubble–wall interactions on bubbling regimes.

Mesoscopic modeling the interaction of two attached-wall cavitation bubbles [PDF]

open access: yesUltrasonics Sonochemistry
A hybrid thermal lattice Boltzmann cavitation model based on a nonorthogonal framework is developed to investigate the interaction of two attached-wall cavitation bubbles. The interaction modes are systematically analyzed, with an emphasis on how varying

Cavitation-driven bubble evolution and load mechanisms in particle-wall multiphase interactions [PDF]

open access: yesUltrasonics Sonochemistry
The interaction among cavitation bubbles, particles, and solid boundaries critically governs energy transfer in fluid systems. This study employs high-resolution numerical simulations to investigate how fluid flow and solid surfaces influence small scale

Simulations of a bubble wall interacting with an electroweak plasma [PDF]

open access: yesJournal of High Energy Physics, 2021
Abstract We perform large-scale real-time simulations of a bubble wall sweeping through an out-of-equilibrium plasma. The scenario we have in mind is the electroweak phase transition, which may be first order in extensions of the Standard Model, and produce such bubbles.

Translation of cavitation bubble near the different walls

open access: yesUltrasonics Sonochemistry, 2023

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 ...

Dynamic behaviour of cavitation bubble close to a flexible wall [PDF]

open access: yesEPJ Web of Conferences, 2022
The dynamic behaviour of cavitation bubble close to a flexible boundary is investigated experimentally. The cavitation bubble is produced as a consequence of an optical breakdown generated by the focus of 532 nm Nd-Yag laser beam.

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
