Precise Void Fraction Measurement in Two-phase Flows Independent of the Flow Regime Using Gamma-ray Attenuation

open access: yesNuclear Engineering and Technology, 2016
Void fraction is an important parameter in the oil industry. This quantity is necessary for volume rate measurement in multiphase flows. In this study, the void fraction percentage was estimated precisely, independent of the flow regime in gas–liquid two-

Void Fraction Measurements Using Neutron Radiography [PDF]

open access: yesNuclear Science and Engineering, 1995
Real-time neutron radiography is being evaluated for studying the dynamic behavior of two-phase flow and for measuring void fraction in vertical and inclined water ducts. This technique provides a unique means of visualizing the behavior of fluid flow inside thick metal enclosures.

Void fraction instrument acceptance test procedure [PDF]

open access: yes, 1994
This acceptance test procedure (ATP) was written to test the void fraction instrument (VFI) and verify that the unit is ready for field service. The procedure verifies that the mechanical and electrical features (not specifically addressed in the software ATP) and software alarms are operating as designed.

Generation of Porous Particle Structures using the Void Expansion Method

open access: yes, 2008
The newly developed "void expansion method" allows for an efficient generation of porous packings of spherical particles over a wide range of volume fractions using the discrete element method. Particles are randomly placed under addition of much smaller

Numerical simulation of bubble generation in a T-junction [PDF]

open access: yes, 2012
We present a numerical study of the formation of mini-bubbles in a 2D T-junction by means of the fluid dynamics numerical code JADIM. Numerical simulations were carried out for different flow conditions, giving rise to results on the behavior of bubble ...

Void Reactivity Coefficient Analysis during Void Fraction Changes in Innovative BWR Assemblies

open access: yesScience and Technology of Nuclear Installations, 2015
The study of the void reactivity variation in innovative BWR fuel assemblies is presented in this paper. The innovative assemblies are loaded with high enrichment fresh UO2 and MOX fuels. UO2 fuel enrichment is increased above existing design limitations

Computer Simulation of Packing of Particles with Size Distributions Produced by Fragmentation Processes [PDF]

open access: yes, 2015
Fragmentation schemes inspired by theoretical results and conjectures of Kolmogorov are applied to produce particle size distributions of different natures, depending on fragmentation parameters. A two-dimensional computer simulation method of packing is

Analysis of the characteristic lengths in the bubble and slug flow regimes generated in a capillary T-junction [PDF]

open access: yes, 2016
We present an analysis of the geometry of the continuous and disperse phases in the bubble and slug flow regimes in air–water mixtures generated in a capillary T-junction of 1 mm internal diameter.
