Mathematical model and numerical solution of laminar film-wisecondensation in inclined tubes abstract
The purpose of the present study is to explore the flow condensation heat transfer characteristics 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 inside periphery of the tube and along its length. A numerical scheme has been used to solve the 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 the available experimental data and the previous theoretical results. It is found that the present work is in better agreement with experimental data compared to the previous results reported earlier in research papers.
