Influence of physical parameters on the collapse of a spherical bubble
Theoretical and Applied Mechanics Letters, 2022 This paper examines the influence of physical parameters on the collapse dynamics of a spherical bubble filled with diatomic gas (κ=7/5). The problem is formulated by the Rayleigh–Plesset dynamical equation, whose numerical solutions are carried out by ...

Mechanics of collapsing cavitation bubbles [PDF]
Ultrasonics Sonochemistry, 2016 A brief survey is given of the dynamical phenomena accompanying the collapse of cavitation bubbles. The discussion includes shock waves, microjets and the various ways in which collapsing bubbles produce damage.

Bubble collapse near porous plates
Journal of Fluid Mechanics, 2023 The collapse of a gas or vapour bubble near a non-porous boundary is directed at the boundary due to the asymmetry induced by the nearby boundary. High surface pressure and shear stress from this collapse can damage, or clean, the surface. A porous boundary, such as a filter, would act similarly to a non-porous boundary but with reduced asymmetry and ...

Controlled Cavitation in Microfluidic Systems [PDF]
, 2007 We report on cavitation in confined microscopic environments which are commonly called microfluidic or lab-on-a-chip systems. The cavitation bubble is created by focusing a pulsed laser into these structures filled with a light-absorbing liquid.

A bubble fission model for collapsing cavitation bubbles
Physics of Fluids, 2004 A bubble fission model that takes into account energy dissipation during violent collapses of cavitation bubbles is introduced by assuming volume conservation and continuity of the gas pressure during instantaneous breakup, invoking either Rayleigh–Taylor instability or high speed microjet formation.

Shock-Induced Bubble Collapse versus Rayleigh Collapse
Journal of Physics: Conference Series, 2015 This paper compares two physical mechanisms for the collapse of a bubble near a rigid wall: a traveling shock-induced collapse and a Rayleigh-like collapse due to a uniform rise of the pressure around the bubble. A multi-material compressible flow solver capable of handling material interfaces under high pressures is used to investigate these two ...

Numerical Study on Single-Bubble Contraction–Rebound Characteristics in Cryogenic Fluids
Applied Sciences, 2022 In cryogenic fluid storage and delivery, the rapid contraction and rebound of bubbles are prone to occur during bubble collapse due to the pressure saltation.
