Hydrodynamic Modeling of Oil–Water Stratified Smooth Two-Phase Turbulent Flow in Horizontal Circular Pipes

In the petrochemical industry, multiphase flow, including oil–water two-phase stratified laminar is more common and can be easily obtained through mathematical analysis. However, there limited analytical model for simulation of flow under turbulent flow. This paper introduces a two-dimensional (2D) numerical method to investigate pressure gradient, field, interface height pipeline cross-section horizontal tube in an smooth Three Reynolds average N–S equation models (k−ε, k−ω, SST k−ω) are involved simulate according finite volume method. The gradient computed given rate using iteration predicted result velocity profile by fit well with several published experimental data, except that large error gradient. k−ω turbulence appears higher accuracy simulating pipe.
