Heat transfer for saturated falling film evaporation on a horizontal plain tube is studied through analysis and experiment to investigate the effects of film flow rate, liquid feed height, and wall superheat. Two models are proposed, both based upon three defined heat transfer regions: the jet impingement region, the thermal developing region, and the fully developed region. The model which uses an experimental correlation for the 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.
