Eulerian-Lagrangian method for simulation of cloud cavitation [PDF]

, 2017
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.

Bremsstrahlung Radiation At a Vacuum Bubble Wall

, 2007
When charged particles collide with a vacuum bubble, they can radiate strong electromagnetic waves due to rapid deceleration. Owing to the energy loss of the particles by this bremsstrahlung radiation, there is a non-negligible damping pressure acting on

State-dependent diffusion coefficients and free energies for nucleation processes from Bayesian trajectory analysis. [PDF]

, 2018
The rate of nucleation processes such as the freezing of a supercooled liquid or the condensation of supersaturated vapour is mainly determined by the height of the nucleation barrier and the diffusion coefficient for the motion across it. Here, we use a

Spatial-temporal correlation and fluctuating propagation characteristics of bubbles based on a coupled model of oscillation and migration

Applied Ocean Research
Bubble oscillation and migration are complex dynamic processes that have been extensively studied for the applications of ocean engineering. However, the intricate coupling and interactions among various parameters that affect bubble oscillation and ...

Influence of drag closures and inlet conditions on bubble dynamics and flow behavior inside a bubble column

Engineering Applications of Computational Fluid Mechanics, 2017
In this paper, the hydrodynamics of a bubble column is investigated numerically using the discrete bubble model, which tracks the dispersed bubbles individually in a liquid column.

Simulation of coalescence, break up and mass transfer in bubble columns by using the Conditional Quadrature Method of Moments in OpenFOAM [PDF]

, 2013
The evaluation of the mass transfer rates and the fluid-dynamics aspects of bubble columns are strongly affected by the intrinsic poly-dispersity of the gas phase, namely the different dispersed bubbles are usually distributed over a certain range of ...

Homogeneous Bubble Nucleation driven by local hot spots: a Molecular Dynamics Study

, 2009
We report a Molecular Dynamics study of homogenous bubble nucleation in a Lennard-Jones fluid. The rate of bubble nucleation is estimated using forward-flux sampling (FFS).

Analysis of Rayleigh-Plesset dynamics for sonoluminescing bubbles [PDF]

, 1998
Recent work on single bubble sonoluminescence (SBSL) has shown that many features of this phenomenon, especially the dependence of SBSL intensity and stability on experimental parameters, can be explained within a hydrodynamic approach. More specifically,
