A small, spherical bubble of high internal pressure is inserted into water at constant ambient pressure as a model of a laser-induced bubble. Its subsequent dynamics near a flat solid boundary is studied in dependence on the distance of the bubble to the

Numerical Study on Taylor Bubble Rising in Pipes
Slug flow is the most common multi-phase flow encountered in oil and gas industry. In this study, the hydrodynamic features of flow in pipes investigated numerically using computational fluid dynamic (CFD) simulations for the effect of slug flow on the ...

Eulerian-Lagrangian method for simulation of cloud cavitation [PDF]
We present a coupled Eulerian-Lagrangian method to simulate cloud cavitation in a compressible liquid. The method is designed to capture the strong, volumetric oscillations of each bubble and the bubble-scattered acoustics.

The effects of arc bubble behaviors and characteristics on droplet transfer are observed with an in-situ X-ray imaging method. The changes in the force acting on the droplet are analyzed at three distinct stages of arc bubble in one life cycle.

Acoustophoretic trapping of particles by bubbles in microfluidics
We present in this paper a simple method to produce strategic acoustic particle capture sites in microfluidic channels in a controlled way. Air bubbles are intermittently injected into a micro-capillary with rectangular cross section during a flow motion

Numerical simulation of the backscattering of pressure waves from a bubble interface
The direct numerical simulations are conducted for the backscattering of incident pressure waves from a bubble with the ghost fluid method in order to understand the formation of secondary cavitation in the high intensity focused ultrasound (HIFU). It is

Non-spherical collapse of an air bubble subjected to a lithotripter pulse [PDF]
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 ...

Numerical simulations of non-spherical bubble collapse [PDF]
A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a ...
