Abstract

A sensor based on the electrical permittivity of the fluid was used to analyze the tomographies of the different patterns that appear in multiphase oil and water flow (Liquid-Liquid). The experimental study was carried out in a borosilicate glass tube with an internal diameter of 25.4 [mm] and length of 12 [m]. The sensor is made up of two 8 x 8 wire flat wire mesh called a wire mesh sensor (WMS). The experiments were carried out with two different oil viscosities, one with 200 [cP] and the other with 60 [cP] at 860 [kg / m3]density with the tube positioned horizontally and slightly inclined at + 5 degrees, to vary the viscosity of the oil, a heat exchanger was used. The analyzed multiphase flow pattern was annular, stratified and dispersed. The tomographies obtained by the WMS were compared with a high-speed camera for the qualitative validation of the results. Twelve models of electrical permittivity were used to study the current fluid regime.
