Nov 17, 2017 · Two-phase flow regimes have often been presented as plots, or maps, with the phase velocities or functions of them on each axis. Earlier maps were named after their authors, for example Griffith-Wallis, Duns-Ros and Taitel-Dukler.

In multiphase flow you will have three-phases or, three-components. Having two components in the liquid phase (oil and water) can throw up further complications, particularly in horizontal flow.

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.

In most cases, the multi-phase flow correlations are based on the flow regimes that we have already discussed. For use in a multi-phase flow correlation, these flow regimes are plotted as Flow Pattern Maps. Examples of the flow pattern maps are shown in Figure 6.11 (for vertical flow) and Figure 6.12 (for horizontal flow).

Figure 1: Flow regime map for the horizontal flow of an air/water mixture in a 5.1cm diameter pipe with flow regimes as defined in figure 2. Hatched regions are observed regime boundaries, lines are theoretical predictions.

the course from an introduction to multiphase flow measurement philosophy and multiphase flows in general, via selection of technology, performance specifications, design considerations to field installation and commissioning and finally the operation of MPFMs. Chapter 3 is new and includes informative references to provide the reader with

Pietro Fiorentini Multiphase Flow Meter (MPFM) is an inline flow metering device, tailored for continuous real-time measurement of the amount of oil, water and gas in the well stream. Reduce CAPEX .

It also deals with the ubiquitous needs of the multiphase-flow modeller, namely pressure drop and phase distribution, i.e., the void fraction and the topology of the phases that determines the flow regimes.

Flow structure maps are the most useful tool in the process of identifying structures formed in multiphase flows. They can be defined as a graphical way to present the transition boundaries of flow structures, depending on the characteristic pa-

Multiphase flow, the simultaneous flow of more than one phase, occurs in many facets of chemical engineering, e.g., distillation, absorption, evaporation, condensation, solvent extraction.
