2. Two-phase flow - Wikipedia

   en.wikipedia.org/wiki/Two-phase_flow

   Different modes of two-phase flows. 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 form of particles, droplets, or bubbles in ...

3. Comparison of pumps - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_pumps

   Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

4. Multiphase flow - Wikipedia

   en.wikipedia.org/wiki/Multiphase_flow

   Gas (white) and oil particles (black) are in a disperse phase. In fluid mechanics , multiphase flow is the simultaneous flow of materials with two or more thermodynamic phases . [ 1 ] Virtually all processing technologies from cavitating pumps and turbines to paper-making and the construction of plastics involve some form of multiphase flow.

5. Centrifugal pump - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump

   Another type of self-priming pump is a centrifugal pump with two casing chambers and an open impeller. This design is not only used for its self-priming capabilities but also for its degassing effects when pumping two-phase mixtures (air/gas and liquid) for a short time in process engineering or when handling polluted fluids, for example, when ...

6. Slip ratio (gas–liquid flow) - Wikipedia

   en.wikipedia.org/wiki/Slip_ratio_(gas–liquid_flow)

   There are a number of correlations for slip ratio. For homogeneous flow, S = 1 (i.e. there is no slip). The Chisholm correlation [2] [3] is: = The Chisholm correlation is based on application of the simple annular flow model and equates the frictional pressure drops in the liquid and the gas phase.

7. Multiphase flow meter - Wikipedia

   en.wikipedia.org/wiki/Multiphase_flow_meter

   Measurement and interpretation of 2 and 3 phase multiphase flow can also be achieved by using alternative flow measurement technologies such as SONAR.SONAR meters apply the principles of underwater acoustics to measure flow regimes and; can be clamped on to wellheads and flow lines to measure the bulk (mean) fluid velocity of the total mixture which is then post-processed and analyzed along ...

8. Darcy's law for multiphase flow - Wikipedia

   en.wikipedia.org/wiki/Darcy's_law_for_multiphase...

   The unknown dependent variables have traditionally been oil pressure (for oil fields) and volumetric quantities for the fluids involved, but one may rewrite the total set of model equations to be solved for oil pressure and mass or mole quantities for the fluid components involved. [7]

9. Separator (oil production) - Wikipedia

   en.wikipedia.org/wiki/Separator_(oil_production)

   In the two-phase units, gas is separated from the liquid with the gas and liquid being discharged separately. Oil and gas separators are mechanically designed such that the liquid and gas components are separated from the hydrocarbon steam at specific temperature and pressure according to Arnold et al (2008). [2] In three-phase separators, well ...
