B annwartA. An iterative procedure wn explained in  about three phase oil-water-gas flow. The model of  is based on a quasi steady state. The first term depending of the shear stress is not used in most of the 1-D analysis ,,,,,. The drift flux model is an special case of the simplified model and the two fluid model is also an important mechanistic model.
PROPIEDADES DEL copy2
The pressure correction schemes can cause convergence problems due to linkage between equations, some modifications mmultifasico the SIMPLE method are explained by  to avoid some convergence problems. The equation 2 describes a relation between the gas velocity and the mixture velocity using the drift velocity u D and the distribution parameter C 0 .
Multiphase Flow 18 3 Y anpingQ. The total pressure drop depends on friction lost, height and acceleration of the fluid. S alagerJ. Its simplicity imply that multufasico can be found fast. On the other hand, the small scale models simulate the multiphase flow tracking the interface, they can show bubbles, slugs and their shapes.
S hohamO. These zones are identified in Figure Li, “A two-phase, two-component model for vertical upward gas-liquid annular flow,” International Journal of Heat and Fluid Flowvol.
They used the same value for C o in both works. Services on Demand Article. Different kind of models has been implemented, it includes simple models as well as more elaborated models. Hibiki, Thermo-fluid dynamics of two- phase flow. Thereby, calibration is not possible at the design time. They found that there is an optimum concentration of water at which the stability of the foam increases, and small quantities of water and surfactants produce a drastic change in the foaminess of the oil.
Due to the variety of condition in the oil industry, it is necessary to fluji models at conditions how they will be used. The continuity equation 5 is formed by a transient term temporal derivativea convective term spatial derivative and a change of phase term.

They find first the void fraction with a representative liquid mixture and then, they calculate the holdup of every liquid. According to SchmidtEdward et al. Ginestra, “A fully-coupled thermal multiphase wellbore flow model for use in reservoir simulation,” Journal of Petroleum Science and Engineeringvol. Finally, the energy conservative equation in terms of enthalpy is presented in 7 .
Journal of Petroleum Sci. The difference between coefficients A and B for both experimental data and synthetic data are shown in 4b and 4c.

The works found in the literature use data from laboratories and real fields tuberis develop the models presented. Two of the most used methods are Newton iteration  and pressure correction scheme ,.
Characteristics of the foam emulsion In order to represent the characteristics of the Foamy Oil, a highly viscous mineral oil with a viscosity of 0. They highlight importance of a correct selection of the flow pattern with an example, in which, stratified and bubbly flow was used to compare results against experimental data.
For each experimental point the hydrodynamic parameters were kept constant with time, namely: Three-phase flow systems for high oil viscosity is a topic that has been calling the attention of the multiphase multitasico research community recently.
