Cross Correlation Based Dispersed Phase Velocity Profile Measurement of Two-Phase Pipe Flow

Abstract

This paper introduces a method of forming up the cross sectional velocity profile of horizontal two-phase flow by adopting a dual-plane Electrical Resistance Tomography (ERT) system and cross correlation method. The preliminary results are presented with numerical simulations, where a pixel-like mesh is used to segment the cross section of the measuring field. The relationship between the peripheral voltages measured from the electrodes with a feature value within a specific pixel is determined. The numerical simulation results show that this method can provide a visual distribution of velocity profile of dispersed phase within a continuous phase in the cross section of the pipeline.
