The principal method of determining flow patterns has been by visual observation through a transparent viewing section and more recently with tomography equipment which typically has limited resolution...

.... IFE has recently developed and demonstrated scale-up rules for the most basic multiphase pipe flows. Earlier, the scaling rules were tested by designing experiments in IFE's medium-scale multiphase flow loop to compare with data from SINTEF's largescale facility. The focus of this paper...

... ABSTRACT In this work, an X-ray system consisting of six cameras was used to obtain instantaneous cross-sectional phase distribution of gas-liquid flow in annuli. The horizontal annulus test section, made of PVC, consisted of an outer pipe of 99 mm inside diameter and an inner pipe of 50 mm...

... ABSTRACT A comprehensive three-phase flow campaign, funded by Equinor as part of the Tanzania gas field development project [1] [2] [3], was carried out in the SINTEF Large Scale Loop at Tiller in 2017–2018. The experiments were conducted in a 94 meter long 8" pipe, with 2.5° inclination at 60...

... are sand particles, hydrates and wax. Depending on the flow rate, fluid condition, pipe size and sand properties, sand particles can either move along as suspended particles in the flow (dispersed), scouring along the pipe wall, as a bed of particles (dunes) or remain stationary. At high flow rates of oil...

...Velocity profiles in stratified two-phase flow: Comparison of measurements and model predictions P Andersson, J Henriksson Schlumberger, SNTC, Norway ABSTRACT One-dimensional models of multiphase flow in pipes are based on averages over the pipe cross section, and traditional models rely on bulk...

... of gas and liquid through vertical pipe sections. The open source CFD framework OpenFOAM has been used for this purpose, employing two different multiphase flow methods. The Volume of Fluid method can be used for the capturing of the liquid-gas interfaces, while the two fluid model approach is typically...

... experiments in low liquid loading flows with high gas rates were conducted in the Large Scale Loop at the SINTEF Multiphase Flow Laboratory. The experiments were conducted in both a near-horizontal 8" pipe, and a vertical 4" pipe, where particular emphasis was put on studying the effect of water cut...

... solutions in flows with low liquid loading. Specifically, maps were generated showing the critical flow rates for which the flow changes from the low-holdup solution to the high-holdup solution. Such maps were created for various pipe diameters, pipe angles, liquid densities, gas densities and liquid...
