Vapor condensation of the pure ethanol on the curvilinear fin was studied theoretically. Optimized profile of the fin surface providing maximum condensate flow rate has been calculated. New experimental rig and condenser with the optimized fin profile have been designed and created. Numerical simulation of the average heat transfer coefficient in depends of temperature drop and interfin space has been performed. It was found that the value of the flooding level of the interfin space significantly affects the intensity of condensation as a whole, however, it does not affect significantly the process of condensation on the upper convex part of the fin surface.
