.... Nevertheless, this flow regime is commonly found in several applications in the oil and gas industry, such as in gas-lift operations, production of gas-condensate wells, and high-gas-volume fraction two-phase flows in general. In addition to that, the accuracy of two-phase flow models for large pipe diameters...

.... The addition of the lipophilic surfactant makes the mineral oil to resemble crude oil behavior. The oil-water mixtures were circulated with a low shear pump in a closed flow loop setup. Four different acrylic pipe diameters (16, 32, 60 and 90 mm) were tested. Water-in-oil stable emulsions were observed from...

.... The objective of this work is to study the influence of the pipe diameter on the flow of water-in-oil emulsions. Pipe flow experiments were carried out with water-in-oil surfactant stabilized emulsions. 0.25% in volume of a lipophilic surfactant (Span 80) in oil Marcol 52 (μ=10 mPa.s) and salt water (3.5...

... that viscosity is a significant parameter for drift velocity which used to be a neglected factor in all previous literature. In this paper the effect of high viscosity in different pipe diameters on drift velocity is investigated using a Computational Fluid Dynamics (CFD) approach. New drift velocity data for 3...
