Pressure drop and holdup in stratified gas‐liquid flow

Abstract

Abstract A mathematical model and an iterative procedure to calculate holdup and pressure drop in horizontal gas‐liquid flow is developed. The predictions of the model agree with well over a hundred data points collected with air‐water and air‐glycerine solutions in 0.0254‐, 0.0381‐, and 0.0508‐m. diameter pilot pipelines. A design procedure using the verified model is presented.
