Al-Yarubi, O.S. and Lucas, Gary (2009) Phase Flow Rate Measurements of Annual Flows. In: University of Huddersfield Research Festival, 23rd March - 2nd April 2009, University of Huddersfield. (Unpublished)

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.
