Gas–liquid two-phase upward flow through a vertical pipe: influence of pressure drop on the measurement of fluid flow rate

The accurate estimation of pressure drop during multiphase fluid flow in vertical pipes has been widely recognized as a critical problem in oil wells completion design. The flow of fluids through the vertical tubing strings causes great losses of energy through friction, where the value of this loss...
