Abstract
— The two-phase flow rate measurements remain a challenging task due its complexity. There are many factors that affect on the measurement process such as the properties of the two phases and the dryness fraction. In the current study, the two-phase flow through three orifice plates with different beta ratios (orifice diameter to pipe inner diameter ratio) of 0.7, 0.63, and 0.5 installed in a horizontal acrylic pipe with an inside diameter of 60 mm has been experimentally investigated to improve the accuracy of the two-phase mass flow rate measurements. The inlet superficial velocities of liquid and gas phases are rated from 0.8 to 2.4 m/s and from 0.0 to 0.79 m/s, respectively. Also, the average gas volume fraction is rated from 0.0 to 61%. The pressure drop through the three orifice plate was measured and the flow patterns were tackled before and after the orifice plate.
The effect of the two-phase flow on the orifice correction factor is studied at different liquid and gas mass flow rate values for the three orifice plates with different beta ratios. Also, a new correlation was introduced for the two-phase correction factor through the three orifice plates.
