Measurements of Gas Holdup and Correlation Velocity for a Vertical Gas/Liquid Pipe Flow Using Electrical Resistance Tomography System

摘要：

Measurements of gas holdup and velocity are required in gas/liquid two-phase flow. Using electrical resistance tomography (ERT) technique,the crosssectional image can be obtained,and hence the gas holdup is estimated. Combining ERT with the cross correlation flow measurement technique,the velocity can be calculated. A digital twin-plane ERT system for use on laboratory was developed. The velocity measurement method based on gas holdup of two plane images cross correlation was described. This paper presented the reconstructed images,gas holdup estimations and correlation velocity. Experiment results showed the feasibility of the presented method.
