Phase Flow Rate Measurements of Annual Flows

Abstract

The Annular flow regime makes measurement of the total liquid flow rate difficult. It is even more difficult to measure the individual flow rate of either the oil or the water. In a vertical Perspex tube (i.d. = 50 mm) using a newly-designed flow loop in the University of Huddersfield, annular flow was established and different measurements were carried out. One possible on-line measurement technique to achieve the oil volume fraction measurement is an automated bypass system using solenoid valves. An ultrasonic flow meter was designed to serve the purpose of measuring the velocity of the gas in the core. In this study, the used techniques include the use of Conductance Flow Meter to measure the liquid film thickness and to obtain the film velocity using the crosscorrelation technique. The results of the present work have shown a good agreement with Zabaras and Dukler’s work which indicates the success of the new measurement techniques
