An in-line oil-water separator has been designed and is investigated for single- and two-phase flow. Numerical single-phase flow results show an annular reversed flow region. This flow pattern agrees qualitatively with results from measurements. In the two-phase flow simulations two different drag laws have been used to model the interaction between the phases. The velocity field of the single- and the two-phase flow is shown to be very similar. However, the oil volume fraction distribution is strongly affected by the choice of the drag law. Furthermore, compared to experimental results for both drag laws the separation efficiency is greatly overestimated
