Abstract
In this article, a novel wire-mesh sensor based on permittivity (capacitance) measurements is applied to generate images of phase fraction distribution and investigate the flow of viscous oil and water in a horizontal pipe. Phase fraction values were calculated from the raw data delivered by the wire-mesh sensor using different mixture permittivity models. Furthermore, these data were validated against quick-closing valve measurements. Investigated flow pattern were dispersion of oil in water (Do/w) and dispersion of oil in water and water in oil (Do/w&w/o). Maxwell-Garnett mixing model is better suited for Dw/o and Logarithimc model for Do/w&w/o flow pattern. Images of time-averaged cross-sectional oil fraction distribution along with axial slice images were used to visualize and disclose some details of the flow.
