... issues related to the transported fluid such as: pressure drop, liquid hold-up, hydrates, corrosion and sand. The recent subsea technology development, Pseudo Dry Gas System (PDGS), has demonstrated that deep water fields (~2000 m) can be transported long distances (~200 km) to existing processing...

... entrainment and deposition have relevant impact on annular flow properties, such as pressure drop and film thickness, as vastly shown in literature. Several authors have described physical mechanisms for droplet entrainment and deposition; many of those are related to disturbance waves. The objective...

One of the key concerns was that the presence of oil, water and MEG increases the frictional pressure drop more than current multiphase models...

... was granted access to use the data for improving the accuracy of the pressure drop predictions in LedaFlow. The experimental results showed that a key element for predicting high-rate low liquid loading flows accurately is to account for the droplets that deposit on the walls in the gas zone, creating a wall...

...). Dispersion viscosities derived from pressure drop measurements increased with higher dispersed phase fraction. However, the relative increase in viscosity was considerably less for the condensate – MEG system when compared with the model system. For all systems, a peak value of the viscosity was reached...

... ABSTRACT We consider the apparent roughness and increased pressure drop associated with the presence of a thin liquid film between the gas and the pipe wall in two- and three-phase stratified-annular gas-liquid flow. The main objective is to improve the pressure drop predictions for near...

... of the sunken riser. There are, however, serious flaws to this approach, the most apparent being the lack of reliable multiphase flow models for flow in annuli, that is, flow between the inner and the outer pipe. Commercial multiphase flow simulators lack the ability to correctly predict pressure drop...

From these experiments, it was concluded that the flowrate at which loading occurs can be predicted by the overall pressure drop curve...

In this work, we compare the velocity profiles determined by OLGA HD against measured data from two-phase oil-water experiments. Additionally, we will show that good pressure drop predictions can be obtained even when...
