Presented is a two-dimensional model of steam condensation on a non-inundated horizontal tube. The model takes into account heat transfer through a thermal boundary layer consisting of the film of condensate flowing down the heat transfer surface, and the gas part of the layer being the steam-air mixture. Results are presented of calculations of the condensation process as a function of tube length. The analysis was performed for different variants of free and forced convection. The obtained results of calculations were compared with the cases of real condenser tubes in operation in the installation of 200 MW power units.
