“…Also, some differences in the predicted flow pattern for high viscous flow was shown by [63], [64] and [65]. It was suggested by [1] that 3D simulation can be used to get a better understanding of flow pattern transitions.…”

In this work a review about the most relevant methods found in the literature to model the multiphase flow in pipelines is presented. It includes the traditional simplified and mechanistic models, moreover, principles of the drift flux model and the two fluid model are explained. Even though, it is possible to find several models in the literature, no one is able to reproduce all flow conditions presented in the oil industry. Therefore, some issues reported by different authors related to model validation are here also discussed. ResumenEn este trabajo se presenta una revisión de los métodos más relevantes en la industria del petróleo para modelar el flujo multifásico en tuberías. Se incluyen desde los modelos simplificados hasta los modelos mecanicistas además de explicar los principios de los modelos drift flux y two fluid. Existe una gran cantidad de modelos en la literatura para simular el flujo multifásico en tuberías, empero, ningún modelo es capaz de reproducir todas las condiciones de flujo multifásico presentes en la industria del petróleo. Finalmente, se mencionan algunos temas en los que se requiere más investigación que lleven a simulaciones con resultados más cercanos a los datos de pozos reales.

“…Matsubara and Naito [10] studied the e ect of liquid viscosity on the ow patterns of airliquid two-phase ow in a horizontal tube with 20 mm diameter and used di erent liquids with the viscosity of 1{11000 mPa.s. Zhao et al [11] investigated the e ect of viscosity changes of oil phase on the characteristics of the gas-viscose oil two-phase ow in a horizontal tube of 26 mm diameter. They also presented that the characteristics of viscous ow of the gas-oil twophase ow are signi cantly di erent from low-viscosity kind of the two-phase ow.…”

Experimental two-phase ow investigation; High-speed photography; Oil-air two-phase ow patterns; Flow maps in inclined pipe.Abstract. In this paper, an experimental study on the ow patterns of two-phase air-light oil ow is performed in a 20 mm diameter pipe with a length of 6 m in di erent orientations with pipe angles in the range of {45 to +45. The ow regimes are captured by a high-speed camera. In the experiments, the following are used: the air with the viscosity of 0.019 mPa.s and the density of 1.2 kg/m 3 as well as the light oil with the viscosity of 2.6 mPa.s and the density of 840 kg/m 3 . During the experiments, di erent ow patterns are observed such as bubbly, slug, smooth strati ed, wavy strati ed, and annular ows. Flow regimes in di erent pipe inclination angles are inspected in a two-phase air-light oil ow, and ow pattern maps are proposed for every pipe inclination angle. In addition, a comprehensive study on the major forces acting on dispersed phase is presented theoretically to perform a thorough discussion on the e ects of pipe inclination angle on transition boundaries between ow patterns in the two-phase air-light oil ow. It is inferred that non-strati ed ows are dominant ow patterns in the upward ows, and strati ed ows are dominant ow patterns in the downward ows.

“…They used air as the gas phase and several types of oils as the liquid phase, with viscosities ranging from 1000cp to 7500cp. Regarding the flow patterns observed, Zhao et al (2013) obtained in their experiments slug, plug, annular and blow-through-slug (a transitional pattern between slug and annular) flow. The most present flow pattern was slug flow, followed by plug flow, which indicates that intermittent flow dominates the flow pattern map for these fluids and setup.…”

“…In the slug flow, a thin oil film was observed above the long bubbles and stratified flow was not observed for any flow rates covered in their measurements. Zhao et al (2013) measured the liquid slug holdup and found no significant impact of liquid viscosity on such parameter. They observed that both the mean liquid holdup of the flow and its pressure gradient increase with the liquid viscosity.…”
