Condensation heat transfer studies for stratified, cocurrent two-phase flow in horizontal tubes

Abstract Condensation heat transfer inside horizontal tubes is investigated for a stratified, cocurrent two-phase flow of vapor and liquid. The analysis takes into account the effects of interfacial shear, axial pressure gradient, saturation temperature level, driving temperature difference and the development of the stratified angle associated with the accumulated condensate layer at the bottom of the tube. The influence of these parameters is evaluated with respect to the peripheral condensate film heat transfer performance for the practically interesting laminar flow range of operating conditions of water-vapor flow. A theoretical predictive method is developed to obtain the overall heat transfer coefficient along the tube length. Results of the theoretical predictions are found to agree favorably with the reported experimental data which cover a variety of fluids with a relatively wide range of operating conditions. A simple, predictive heat transfer coefficient correlation is proposed from the numerical solution by means of regression analysis.
