INTRODUCTION Separation of oil-water systems has long been an important research topic Separation of oil-water systems has long been an important research topic Multiphase flow dynamic of these devices is a main phenomenon, which has great influence on efficiency and commercial compatibility of the entire process.

INTRODUCTION Phenomenological models have earlier been widely used to describe such flows, but these simulations are not well suited for so called scale-up Phenomenological models have earlier been widely used to describe such flows, but these simulations are not well suited for so called scale-up up-to-date CFD tool may successfully simulate multiphase systems for a variety of conditions and pattern sizes without using prior experimental data for the concrete apparatus. up-to-date CFD tool may successfully simulate multiphase systems for a variety of conditions and pattern sizes without using prior experimental data for the concrete apparatus.
