... physics of annulus flows. A new six-camera X-ray tomography system is mounted on IFE's Well Flow Loop and used to reveal internal flow structures for a wide range of gas-liquid and oil-water flows. The initial campaign is reported in the current paper. INTRODUCTION On the 20th of April 2010, explosion...

... program (2) found that the two-phase oil-water flow rate increases with the addition of water in oil-water emulsions, compared to that of single-phase oil. In addition, the researchers observed a peak when the dispersed flow regime transited to stratified with mixing flow. different viscosity...

.... The inclination of a pipeline is a crucial factor considerably influencing the oil-water flow. Small deviations from horizontal alignment can cause large changes of the local phase fractions and consequently the pressure gradient. Available data is, however, often limited to low viscosity oils and small...

... flow regions while the reverse was the case at downward inclination in the same flow regions. Introduction Oil-water flows are often encountered in chemical industries, and even more so in petroleum industries because of the simultaneous production of oil and water from aging oil wells in recent...

... Abstract This paper reports an effort to investigate the effect of flow velocities and inlet configurations on horizontal oil-water flows in a 32 mm ID acrylic pipe using water and an aliphatic oil (Exxsol D140) as test fluids. The flows of interest were analysed using pressure drop...

... ABSTRACT The effect of drag reducing polymers on interfacial characteristics in stratified oil-water flows was studied in a horizontal 14 mmID acrylic pipe, using tap water and a middle distillate oil (ρ = 830 kgm-3, μ = 0.0055 kgm-1s-1) as test fluids. The polymer Magnafloc 1011 was added...

... ABSTRACT In this paper we present experiments of oil-water flow and a simplified turbulent diffusion model which predicts phase fractions in the cross section of the pipe. We find that the model can describe the observed cross sectional phase fractions fairly well when the mixture velocity...
