Multiphase flow of oil and water in pipes is a subject of great interest for the petroleum industry. Depending on the volumetric flow of each phase a number of different patterns can occur and, among them, the stratified flow pattern is of particular interest, because it is usually seem in horizontal pipelines. This paper presents simulations of this flow pattern using interFoam, a solver based on the VOF interface capturing method and available in OpenFOAM. The computational results are compared with experimental data and the predictions using an unidimensional model for global and local parameters of the flow, like pressure drop, water hold up and velocity profiles. The comparison shows good overall results for pressure drop and hold up, while the velocity profile tends to be under predicted. The CFD model is also evaluated by its capability to predict the position and shape of the fluids interface.
