Numerical Study of the Pulsation Process of Spark Bubbles under Three Boundary Conditions
Journal of Marine Science and Engineering, 2021 In this study, a compressible three-phase homogeneous model was established using ABAQUS/Explicit. These models can numerically simulate the pulsation process of cavitation bubbles in the free field, near the flat plate target, and near the curved ...

Sonoporation from Jetting Cavitation Bubbles [PDF]
Biophysical Journal, 2006 The fluid dynamic interaction of cavitation bubbles with adherent cells on a substrate is experimentally investigated. We find that the nonspherical collapse of bubbles near to the boundary is responsible for cell detachment. High-speed photography reveals that a wall bounded flow leads to the detachment of cells. Cells at the edge of the circular area

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.

Frontiers in Energy Research, 2022 The internal temperature distribution and evolution in cavitation bubble can be investigated numerically by a thermal lattice Boltzmann method. The simulation results are consistent with the calculational results of the Rayleigh-Plesset equation and the ...

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.

Cavitation in soft matter [PDF]
, 2020 Cavitation is the sudden, unstable expansion of a void or bubble within a liquid or solid subjected to a negative hydrostatic stress. Cavitation rheology is a field emerging from the development of a suite of materials characterization, damage ...

Cavitation And Bubble Dynamics [PDF]
, 1995 Abstract The book describes and explains the fundamental physical processes involved in bubbly dynamics and the phenomenon of cavitation. The study of cavitation and bubbly flow applies to many areas of interest; from valve damage in hydroelectric equipment, ship propellors and internal combustion engines to the performance of ...

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.

Non-spherical collapse of an air bubble subjected to a lithotripter pulse [PDF]
, 2008 In order to better understand the contribution of bubble collapse to stone comminution in shockwave lithotripsy, the shockinduced and Rayleigh collapse of a spherical air bubble is investigated using numerical simulations, and the free-field collapse ...

A numerical model for cloud cavitation based on bubble cluster
Theoretical and Applied Mechanics Letters, 2017 The cavitation cloud of different internal structures results in different collapse pressures owing to the interaction among bubbles. The internal structure of cloud cavitation is required to accurately predict collapse pressure.
