Heat transfer for saturated falling-film evaporation on a horizontal smooth tube has been studied through analysis and experimentation to investigate the effects of film flow rate, liquid feed height, and wall superheat. Two models have been proposed, both based on three defined heat transfer regions: the jet impingement region, the thermal developing region, and the fully developed region. The model that uses an experimental correlation for heat transfer in the fully developed region compares favorably with experimental data and other predictions reported for the case where the liquid feed is in a sheet.
