The investigation aimed to determine the effects the gaseous phase may cause on the pump volumetric efficiency. Data obtained on a specially designed test facility is presented and analyzed as a first step before developing a semi-empirical model to predict the performance of the pump under two-phase flow conditions. Preliminary results, based on one-phase and two-phase runs, demonstrate important features introduced on the pump performance once the gas-phase is included in the processenResearch Subject Categories::TECHNOLOGY::Engineering mechanicsmechanical engineeringoil artificial-lift pumping unitArticle
