.... 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 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...
