Transient gas–liquid flowTwo phase flow in a hilly terrain pipeline, composed of uphill and downhill sections, exhibits a complex transient behavior at low flow rates owing to the accumulation of liquid in the low elbows and gas in the top elbows. At low flow rates gravity has a dominant ...

This work presents an experimental investigation on the flow patterns of gas-liquid two-phase flow in pipeline S-shaped flexible riser system.The test loop consists of a horizontal pipeline 114 m in length and 50 mm in i.d.,a-2°downward inclined pipe 16 m in length,and an S-shaped ris...
Liquid holdupGasliquidliquid three-phase co-current flow commonly occurs in the oil & gas production pipelines. The dynamics of three-phase flow are more complex than single and two-phase flow. High pressure drop and liquid holdup are common flow assurance problems in the upstream oil and gas...

Low liquid loading gas /liquid flow is frequently encountered in condensate natural gas transmission through long distance pipelines. In this review the typical flow phenomena of low liquid loading gas /liquid pipe flow are described based on the experimental measurements and observations conducted by ...
An experimental study on the flow patterns and their transitions for gas-liquid two-phase upward flow in an inclined tube is carried out ,with the inclination angle ranging from 0to 20 degree,Correlatins are derived to predict the transitions from annular flow to slugflow,from dispersed bubble...
