Interaction between two spherical bubbles rising in a viscous liquid [PDF]
, 2011 The three-dimensional flow around two spherical bubbles moving in a viscous fluid is studied numerically by solving the full Navier-Stokes equations. The study considers the interaction between two bubbles for moderate Reynolds numbers (50 ≤ Re ≤ 500, Re

Multibubble Sonoluminescence from a Theoretical Perspective
Molecules, 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
AIP 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]
International Journal of Fluid EngineeringMultibubble 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.

Bubble simulations with an interface tracking technique based on a partitioned fluid-structure interaction algorithm [PDF]
, 2010 Numerical techniques frequently used for the simulation of one bubble can be classified as interface tracking techniques and interface capturing techniques. Most of these techniques calculate both the flow around the bubble and the shape of the interface

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

A derivation of the stable cavitation threshold accounting for bubble-bubble interactions
Ultrasonics Sonochemistry, 2017 The subharmonic emission of sound coming from the nonlinear response of a bubble population is the most used indicator for stable cavitation. When driven at twice their resonance frequency, bubbles can exhibit subharmonic spherical oscillations if the acoustic pressure amplitude exceeds a threshold value.

Conditions for the sliding-bouncing transition for the interaction of a bubble with an inclined wall [PDF]
, 2016 In this study we analyze the interaction of a single rising bubble with an inclined wall. We conduct experiments considering different liquids and bubble sizes, to cover a wide range of Reynolds and Weber numbers, with wall angles from nearly horizontal ...

Defect Formation Rates in Cosmological First-Order Phase Transitions [PDF]
, 2001 In cosmological first-order phase transitions, the progress of true-vacuum bubbles is expected to be significantly retarded by the interaction between the bubble wall and the hot plasma.
