Pressure drop and holdup predictions in horizontal oil–water flows for curved and wavy interfaces

Chemical Engineering Research and Design, 2015
AbstractIn this work a modified two-fluid model was developed based on experimental observations of the interface configuration in stratified liquid–liquid flows. The experimental data were obtained in a horizontal 14mmID acrylic pipe, for test oil and water superficial velocities ranging from 0.02m/s to 0.51m/s and from 0.05m/s to 0.62m/s ...
