Vortex ring and bubble interaction: Effects of bubble size on vorticity dynamics and bubble dynamics

Physics of Fluids, 2023
Bubbly turbulent flows involve complex interactions between bubbles and vortices, in which their size ratio plays a critical role. The present work investigates an idealization, namely, the interaction of a single air bubble with a (water) vortex ring, with the focus being on the effects of the bubble-to-vortex core size ratio (Db/Dc,o) on the bubble ...

An introduction to bubble dynamics

Physical Chemistry Chemical Physics, 2007
The creation, understanding and control of mesoscopic chemical objects are at the core of many areas of chemistry and physics. Their preparation depends on a variety of nucleation and aggregation processes and they are exploitable for practical purposes, including fabrication techniques. At the opposite end, are cavitation phenomena.

Cardiovascular Bubble Dynamics

Critical Reviews in Biomedical Engineering, 2005
Gas bubbles can form in the cardiovascular system as a result of patho-physiological conditions or can be intentionally introduced for diagnostic or therapeutic reasons. The dynamic behavior of these bubbles is caused by a variety of mechanisms, such as inertia, pressure, interfacial tension, viscosity, and gravity.

Symmetry in bubble dynamics

Communications in Nonlinear Science and Numerical Simulation, 2004
This work reviews the study of the symmetry approach in bubble dynamics and its applications to nonlinear acoustics. Point symmetries of the respective model equations are used to study the dynamics of single bubble pulsations, tethered bubbles and the distribution of coagulating bubbles.

Bubble Dynamics for Single Bubble Sonoluminescence

Journal of the Physical Society of Japan, 2001
Problems involved in the bubble dynamics models which have been suggested to explain the sonoluminesence phenomena from a single bubble under ultrasound were discussed. One of the problems is proper choice of the time scale of the driving force, which is related to numerical artifacts due to the mismatch between the natural frequency of an oscillator ...
