Abstract: The aim of the European project Multiphase Flow Metrology in the Oil and Gas Sector is to reduce the measurement uncertainty under field conditions by an intercomparison study. In this context multiphase flow simulations using computational fluid dynamics (CFD) should help to understand the differences between the different flow loops. According to the experimental setup within the project, this contribution focuses on the flow of water, oil, and gas in a 12 m long horizontal pipe of diameter D 0 : 104 m . Different superficial gas and liquid velocities lead to different flow patterns, namely stratified, stratified wavy and slug flow. The paper shows the dependence of the flow pattern characteristics on the superficial velocities, fluid properties, mesh and boundary conditions used in the CFD model.
