Abstract
Using a mechanistic approach, equations are developed to describe the stratified cocurrent flow of gas‐liquid mixtures in horizontal pipes. An iterative method is suggested for their solution.Experimental data were collected using air‐oil mixtures in a one inch 1. D. by 101 ft. long acrylic pipe. Pressure drop and average in situ liquid volume fraction are presented as a function of the superficial gas velocity and are compared with predicted results from this study and other models reported in the literature.Visual observation of flow patterns and their transitions are indicated on the tentative flow pattern map of Govier and Aziz(1).
