http://oilproduction.net/files/03-ENGINEERING_DESIGN_GUIDELINES_fluid_flow_two_phase_hydraulics_rev_web.pdf In fluid mechanics, two-phase flow is a flow of gas and liquid — a particular example of multiphase flow. Two-phase flow can occur in various forms, such as flows transitioning from pure liquid to vapor as a result of external heating, separated flows, and dispersed two-phase flows where one phase is present in the … See more The widely accepted method to categorize two-phase flows is to consider the velocity of each phase as if there is not other phases available. The parameter is a hypothetical concept called Superficial velocity See more Several features make two-phase flow an interesting and challenging branch of fluid mechanics: • Surface tension makes all dynamical problems See more • Multiphase flow • Buckley–Leverett equation • Darcy's law for multiphase flow (for flow through porous media such as soil) See more Historically, probably the most commonly studied cases of two-phase flow are in large-scale power systems. Coal and gas-fired power stations used very large boilers to produce steam for use in turbines. In such cases, pressurised water is passed through heated … See more Gurgling is a characteristic sound made by unstable two-phase fluid flow, for example, as liquid is poured from a bottle, or during gargling See more Modelling of two phase flow is still under development. Known methods are • Volume of fluid method • Level-set method • Front tracking by Gretar Tryggvason See more
