SINOPSIS

During the given work the questions on the development of recommendations on updating a condensation model in cylindrical channels of various orientations are considered for down flow of phases in the code SOKRAT, the bank of experimental data and requirements to them are analyzed, and new closing models in the code are verified. The closing models on the heat transfer coefficient and hydraulic resistance, which are developed within the given work, allow satisfactory calculation of the parameters of condensation processes in pipes of various orientation in a wide range of steam speeds (for saturated and superheated steam) and for all modes of film flow. The verification of the given models has shown good agreement with the experimental data.
