... ABSTRACT Experiments were performed with propose of mapping the flow patterns in two-phase flow in an upward inclinable 60 mm ID and 6 m long Plexiglas pipe. Air and viscous oil were used as working fluids and degree of inclination changed from 10 ? to 78 ?. Measurements includes pressure drop...

Two commercially available anti-agglomerant additives (AA-1 and AA-2) were tested in gas / condensate / water system at two water cuts under different multiphase flow regimes. The tests were analysed based on pressure, temperature and pressure drop measurements...

The new model also properly accounts for pipe inclination, diameter, and surface tension effects. pressure drop...

...) systems, which have been observed in modeling to under predict pipeline pressure drop. This is a significant issue because the pressure margins in onshore gathering systems are tight and, in some instances, a ±1 bar difference in expected pressures can dictate how the system is operated. The primary...

In addition, traversing gamma densitometers were mounted on each of the two near-horizontal sections to measure the time-averaged liquid distribution and volume fractions. In this campaign...

... s). Although data are available for small pipes (diameter below 0.03 m), there are very little relevant data for viscous oil flows in large diameter pipes with viscosity above 0.05 Pa s. This means that there is a considerable uncertainty related to holdup and pressure drop predictions for heavy oil...
