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. 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 ...

4. Multiphase flow - Wikipedia

   en.wikipedia.org/wiki/Multiphase_flow

   Three-phase, gas-liquid-liquid flows: mixtures of vapors and two immiscible liquid phases are common in chemical engineering plants. Examples are gas-oil-water flows in oil recovery systems and immiscible condensate-vapor flows in steam/hydrocarbon condensing systems. [ 20 ]

5. Wet gas - Wikipedia

   en.wikipedia.org/wiki/Wet_gas

   A Test separator which determines the phase flow rates by physical separation of the liquid from the gas, with each phase then metered separately. This method provides information on all phases which can then be used to calculate the correction required for a meter and to check the gas flow through the meter.

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. Flow conditioning - Wikipedia

   en.wikipedia.org/wiki/Flow_conditioning

   On the other hand, in two-phase flows, the meter consistently gives negative errors. The use of flow conditioners clearly affects the reading of the meter in aerated liquids. This phenomenon can be used to get fairly accurate estimate of flow rate in low gas volume fraction liquid flows. [16]
