Abstract
An analytical prediction of two-phase annular flow with liquid entrainment is presented. The solution is obtained by considering the momentum and mass-transfer components of the interfacial shear and showing that the momentum term is dominant within the liquid film, while the mass-transfer term is the important component within the gas core. An expression is derived for the interfacial shear in terms of liquid film thickness, and this equation is used: 1. (a) To correlate the available CISE film thickness data in circular pipes with two-phase flow of water or alcohol and argon or nitrogen at various pressures. 2. (b) To predict liquid film thickness, liquid film flow rate, and liquid entrainment in the gas core. Typical results are presented for steam-water mixtures flowing in circular pipes at high pressure. 3. (c) To compare the predicted values of liquid film thickness and flow rate with reported measurements in upwards, downwards and horizontal flow.
