This paper reviews the available information for estimation of heat transfer during film condensation in tubes and annuli. Emphasis is on those fluids which are used in air conditioning and refrigeration. These are ammonia, halocarbon refrigerants, and water. Tables are provided which summarize the available experimental data giving the range of important parameters covered in various studies. Among the topics covered are condensation of low velocity and high velocity vapors, effects of superheat and noncondensibles, effect of oil. effect of return bends, and interfacial phase change resistance. Predictive techniques and experimental data are critically reviewed and recommendations for design calculations are made. Information on further verification of the Shah correlation is also given.
