... extent of liquid-gas separation. The geometry of those systems has a downward annular flow that can contribute not only for instabilities such as severe slugs, but also to an excessive gas fraction at pump intake, causing the phenomenon known as gas-lock. This study intends to characterize the fluid...

... A fast pseudo-composition model is put forth to accurately predict the gas mass fraction (GMF) of production fluid. This model accurately predicts retrograde behaviour characterized by a region in PVT space where decreasing pressure increases liquid fraction. While tuned to normal operating...

... is recorded with a high speed video camera. The tested gas velocities (1–4 m/s) did not give large entrained droplet fractions. The effect of water is to reduce the entrainment and pressure drop. OLGA predicts the pressure drop quite well. 1. INTRODUCTION In order to design multiphase transport lines...

... (Hewitt, 2005). In both horizontal and vertical pipe flows, the phases can assume various geometric patterns or topologies (e.g. bubbly, slug, annular, mist) depending on the phasic volumetric flow rates, pipe diameter and inclination. In addition, the relative phasic volumetric fraction can change along...
