Interaction of a vortex ring with a single bubble: bubble and vorticity dynamics
Journal of Fluid Mechanics, 2015The interaction of a single bubble with a single vortex ring in water has been studied experimentally. Measurements of both the bubble dynamics and vorticity dynamics have been done to help understand the two-way coupled problem. The circulation strength of the vortex ring (${\it\Gamma}$) has been systematically varied, while keeping the bubble ...

A model for bubble–bubble and bubble–wall interaction in bubble formation
AIChE Journal, 2005AbstractA theoretical model for bubble formation at a submerged orifice has been developed, which takes into account the interaction between the column wall and the growing bubble at the orifice, as well as the interaction between subsequent bubbles formed and detached from the orifice.

Effects of liquid compressibility on bubble-bubble interactions between oscillating bubbles
Journal of Hydrodynamics, 2016The mutual interaction between cavitation bubbles plays an important role in the physical processes of cavitation. In this paper, a complete model is developed for modelling the mutual interaction between cavitation bubbles with the effects of liquid compressibility fully included.

Investigation and modeling of bubble-bubble interaction effect in homogeneous bubbly flows
Physics of Fluids, 2010The effect of bubble-bubble interaction in homogeneous bubbly flow is investigated by direct numerical simulation and a bubbly mixture model for bubbly shock flows at void fraction 0.4%–13%. It is found that the bubble-bubble interaction effect is significant at void fraction higher than O(1)% and decreases the amplitude and wavelength of the ...

Experimental detection of bubble–bubble interactions in a wall-sliding bubble swarm
International Journal of Multiphase Flow, 2004Abstract Bubble–bubble interactions in a wall-sliding bubble swarm are investigated experimentally using a particle tracking velocimetry (PTV) technique. Firstly, the drag coefficient of a single wall-sliding bubble is measured, in which the distance between the wall and the bubble interface is much shorter than the average bubble diameter. Secondly,

Bubble-bubble interaction for Lagrangian treatment of multi-component flow
Annals of Nuclear Energy, 1997Abstract Interaction between bubbles for the simple case of a small spherical bubble in the vicinity of a much larger bubble — both rising in stationary liquid — with no mass transfer between liquid and vapor phases, has been studied numerically. The effect of the motion of the larger bubble on the dynamics of the smaller bubble has been determined ...

Journal of Applied Physics, 1990
This paper is concerned with a basic study of optical cavitation or cavitation induced by a high intensity laser beam. The work deals with the collective behavior of several bubbles induced independently and simultaneously. The experimental setup to produce and to visualize bubbles and shock waves in the liquid (water) is described. Bubbles dynamics in

Bubble–bubble interaction effects on multiple bubbles dynamics in an ultrasonic cavitation field
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2019A vibratory erosion test rig is used to study the cavitation erosion of 6061 alloy. Some craters and material fracture are found on the specimen surface at the beginning of test. A cavitation model in an ultrasonic field is developed by applying the bubble–bubble interaction effect into Keller–Miksis equation to obtain the bubbles dynamic ...
