Analysis of bubble distribution in a multiphase rotodynamic pump

Engineering Applications of Computational Fluid Mechanics, 2019
Recent researches show that the pressure increment of a multiphase pump is affected by bubble size and distribution. In order to study the bubble distribution characteristics in such pumps, a novel approach describing the variable bubble size in the pump

Growth laws and self-similar growth regimes of coarsening two-dimensional foams: Transition from dry to wet limits

, 2012
We study the topology and geometry of two dimensional coarsening foams with arbitrary liquid fraction. To interpolate between the dry limit described by von Neumann's law, and the wet limit described by Marqusee equation, the relevant bubble ...

Preliminary analyses on decontamination factors during pool scrubbing with bubble size distributions obtained from EPRI experiments

Nuclear Engineering and Technology, 2021
In this paper, from a review of the size distribution of the bubbles during pool scrubbing obtained from experiments by EPRI, we apply the bubble size distributions to analyses on the decontamination factors of pool scrubbing via I-COSTA (In-Containment ...

Cumulative distribution functions associated with bubble-nucleation processes in cavitation

, 2010
Bubble-nucleation processes of a Lennard-Jones liquid are studied by molecular dynamics simulations. Waiting time, which is the lifetime of a superheated liquid, is determined for several system sizes, and the apparent finite-size effect of the ...

Lorenz Curves, Size Classification, and Dimensions of Bubble Size Distributions [PDF]

Entropy, 2009
Lorenz curves of bubble size distributions and their Gini coefficients characterize demixing processes. Through a systematic size classification, bubble size histograms are generated and investigated concerning their statistical entropy. It turns out that the temporal development of the entropy is preserved although characteristics of the histograms ...

The pseudo-homogeneous flow regime in large-scale bubble columns: experimental benchmark and computational fluid dynamics modeling

Petroleum, 2019
A precise prediction of the fluid dynamics in bubble columns is of fundamental importance to correctly design “industrial-scale” reactors. It is known that the fluid dynamics in bubble columns is related to the prevailing bubble size distribution ...
