A CFD modeling of oil-water flow in pipeline: Interaction analysis and identification of boundary separation

The aim of this study is to simulate the flow of emulsion (immiscible liquids) which is a complex phenomenon in the petroleum industry. In this study, three types of emulsions (O/W) were simulated usingby CFD which has been applied to predict the interaction behavior of oil with water for differentemulsions (25%Oe75%W, 50%Oe50%W and 75%Oe25%W). Numerical modeling illustrated that the obtained results of the velocity profiles were very good agreement with the experimental data for threetype of emulsions. In addition, the analytical model of interaction analysis and identification of boundaryseparation for two-phase flow approve with the experimental data available, despite the emulsionsremain to be more difficulty due to the complex chemical reactions. The results of this study can providethe best solutions for corrosion during hydrocarbons transportation. Thus, CFD approach is recommended to use for numerical investigates due to the high accuracy.
