Based on the drift-flux model, a new mathematical formulation was developed to predict natural separation efficiency. The new model presented in this work considers the effect of the slip velocity in the radial direction, variable neglected in previous simplified models. In addition, a correlation for this effect was obtained by fitting the model to experimental data. Good agreement of this simplified model with the experimental data for not only lower but also for higher gas and liquid flow rates has shown the important effect that the slip velocity in the radial direction has in the prediction of natural separation.
