Flow regime in pipe

WebSlug flow is a destructive, intermittent multiphase flow pattern that has a sequence of elongated bubbles followed by a segment of liquid below the bubble bottom. The hydrodynamics of the slug flow pattern are the most prevalent and complex flow patterns, and the intermittency can cause instabilities in systems where it forms. WebApr 6, 2024 · The FIV response and flow pattern evolution are examined with a gas flow rate of Qg = 4–12 kg/s and a liquid flow rate of QL = 96–288 kg/s. When the gas–liquid flow passes through the jumper, the flow regime subsequently presents the slug flow, bubble flow, churn flow and imperfect annular flow.
