... ABSTRACT The Gannet oil export pipeline is operating at relatively low flow rates. At these low flow rates, there is potential to have a flow regime with laminar flow instead of with turbulent flow. Therefore, the viscosity, or rather the rheological properties, of this oil are essential...

... are water and air, for superficial liquid velocities ranging from 0.2 to 0.7 m/s, and superficial gas velocities ranging from 0.1 to 30 m/s. From the experimental observations of flow regimes in diameters larger than 97 mm, churn flow is observed under conditions that slug flow would be expected in smaller...

... in larger diameter pipes including slug and churn flows in horizontal and vertical pipes. WMS is a state-of-the-art device which yields instantaneous void fraction distributions at pipe cross-sections. Several case studies in slug and churn flow regimes, which are widely observed in the oil and gas...

... with the turbulent field of the gas flow. Introduction Stratified gas/liquid flow is a flow regime that is often in industries such as petroleum, chemical processing and nuclear. This specific flow regime occurs when the flow rate of each phase is low enough, i.e. below the onset of intermittent flows...

... series of measurement from these two types of instruments for three-phase flow is performed. The focus is on the volume fraction of gas in the liquid slug. A comparison of the measured results from these two instruments is conducted, and the effect of water cut and oil-water flow regime on the void...

Sand transport characteristics and minimum transport conditions, MTC, in water and air-water flows were visually obtained. MTC for sand transportation were overlaid on air-water flow regime maps for downhill, dip and uphill...

All friction and slip relations, and the transition between flow regimes, are continuous and smooth for robustness, easy tuning and optimization. The equations are solved numerically using the Strongly Implicit Mixture Flux (SIMF) method developed...
