摘要

A new mechanistic model to predict the natural separation efficiency in vertical pumped wells has been developed. The model is based on the combined phase momentum equations and a general slip clousre relationship. New drag coefficient correlations have bene developed corresponding to the bubbly (i.e.undistorted particle) and churn-turbulent flow regimes. The model indicates that the natural separation efficiency depends strongly on geometry, void fraction and in-situ gas flow rate.
