Research into gas‐liquid flow dynamics in vertical pipelines has revealed that the interplay between the gas and liquid phases becomes considerably more complex when surfactants are introduced.

A simple-to-use correlation has been developed which better predicts liquid holdup in gas-condensate transmission, two-phase flow pipelines. Research for the correlation is based on data from Iran's ...

A numerical and experimental study was carried out to investigate the two-phase flow fields of the typical three valves used in the multiphase pumps. Under the gas ...
