Critical Review of Analytical Correlations for Two-Phase Flow Regime Transitions

Abstract

Two sets of analytical correlations describing transitions between two-phase flow regimes are reviewed and discussed. One set, based an mechanistic models, is due to Taitel and Dukler; the other, based on experimental correlations, is due to Weisman and coworkers. The T-D set is preferred for horizontal flow, whereas the Weisman set seems preferable for vertical flow. A Computer code (FLOP) based on the T-D theory is described and applied to validate the theory.
