Abstract: The purpose of this study is to study the flow condensation heat transfer properties in tubes with different inclination angles. A single inclined tube will be considered. A three-dimensional physical model has been developed which allow .; for considering thermal and hydrodynamic changes around the periphery of the tube and along its length. A numerical scheme has been used to solve equations of continuity, momentum and energy. The results show that the variation of the inclination angle significantly affects the condensed liquid thickness and the mean heat transfer coefficient. The results of the present study for the overall mean heat transfer coefficient and condensate thickness are compared with available experimental data and previous theoretical results. It has been found that the present work is in better agreement with experimental data compared to previous research reports reported earlier.
