Analysis of a Microwave Void Fraction Meter

IEEE Transactions on Industrial Electronics and Control Instrumentation, 1975
The eigenvalue problem of an open-ended, dielectric loaded, circular cylindrical resonator is investigated by the boundary value and numerical techniques to compute the volumetric void fraction of gas bubbles in organic oil coolants used in some modern nuclear reactors.

DETERMINATION OF VOID FRACTION BY IMAGE PROCESSING

2016
Void fraction is one of the key parameters fordefining the characteristics of a two phase flow. However, determination ofvoid fraction is not easy due to changing conditions of flow and the type offluid. In literature, there are plenty of works on determination of voidfraction in two-phase flow in a pipe or channel which uses psychical parametersand ...

Void fraction prevision in LCM parts

The European Physical Journal Applied Physics, 2001
The formation of defects during the LCM processing of composite parts depends on various injection parameters. Industrial users need to realize pieces with good physical and mechanical properties and appearance. This requires to predict what is named a “processability window”.

Void fraction distributions in a kettle reboiler

Experimental Thermal and Fluid Science, 1997
Abstract The void fraction and pressure distribution in shell-side boiling have been experimentally investigated. These data were collected from a horizontal tube bundle test section capable of modeling a kettle reboiler and a submerged evaporator. Kettle reboiler void fraction and pressure distributions were investigated for heat fluxes of 10, 30 ...

Void Fraction—Empirical Methods

2017
The chapter begins by describing the principles of the various methods available for measuring the void fraction ; these include photographic techniques optical or electrical techniques that produce point measurements of the void fraction , etc. One can obtain point measurements, chordal averages, cross-sectional averages or volume averages in the two ...

On void fraction and the nature of porous solids

Advanced Materials, 1996
A new unified model of nanoporous materials, based on a relationship between void fraction and structure, is introduced. The reduction of the complex pore system to a single void and the dense framework components t a single dense shell is shown to help in revealing the system of organization determining the structures of materials such as zeolites ...

The Role of Void Distributions on Void Fraction Measurements

1978
The distribution of voids in a nuclear reactor is of great importance due to their effect on the neutron flux and on the reactor dynamic characteristics in addition to the well known thermohydraulic problems they create. The possibility of using scattered neutrons to measure voids in a liquid flow is investigated experimentally.
