Abstract <p>Filmwise condensation of vapor remains the primary heat transfer mechanism in most modern industrial condensers. Although the use of finned tubes for heat transfer enhancement during condensation has a long history and proven effectiveness, the selection of optimal finning parameters is still often carried out empirically, without a rigorous theoretical basis. This review, being part of a series of brief reviews by the authors on studies of hydrodynamics and heat transfer during vapor condensation on smooth and finned tubes, systematizes the criteria for selecting geometric fin parameters depending on the properties of the working fluid and the characteristics of the finned tube material. The proposed empirical and semi-empirical correlations will make it possible to evaluate the finning efficiency of tubes for a specific heat exchanger and to determine the economic feasibility of its application. The findings presented will contribute to the further transition of the thermal power and refrigeration industries toward next-generation condensers.</p>
