Oil-Water two-Phase Flow Inside T-Junction [PDF]
Journal of Hydrodynamics, 2008 Abstract The oil / water two-phase flow inside T-junctions was numerically simulated with a 3-D two-fluid model, and the turbulence was described using the mixture κ - ɛ model. Some experiments of oil / water flow inside a single T-junction were conducted in the laboratory.

Overview of Oil-water Two-phase Flow Pressure Drop Theory
Academic Journal of Science and Technology, 2023 This is a review of the existing pressure drop theories for dispersed and annular flow in oil and water phases in straight wells is presented. The flow classification criteria, pressure drop calculation methods are outlined. For the dispersed flow, the homogeneous flow model and the two-fluid model are introduced.
