摘要/Abstract

摘要： This paper presents the characteristics of a double helix capacitance sensor formeasurement of the liquid holdup in horizontal oil-water two-phase flow. The finite elementmethod is used to calculate the sensitivity field of the sensor in a pipe with 20 mm inner diameter and the effect of sensor geometry on the distribution of sensitivity field is presented. Then, a horizontal oil-water two-phase flowexperiment is carried out to measure the response of the double helix capacitance sensor, in which a novelmethod is proposed to calibrate the liquid holdup based on three pairs of parallel-wire capacitance probes. The performance of the sensor is analyzed in terms of the flow structures detected by mini-conductance array probes.
