Combined free and forced convection laminar film condensation on an inclined circular tube with isothermal surface
Laminar film condensation on an inclined circular tube, under the condition of combined free and forced convection, is analyzed. The assumptions are as in the analysis of Shekriladze and Gomelauri (1966) for the horizontal tube case. In addition, some approximations are introduced for the determination of the interfacial shear stress. The resultant governing equation, in special cases, yields the known analytical solutions of horizontal and vertical tubes, which were obtained in previous studies. A numerically-obtained solution reveals the effects of vapor velocity and gravity force on local and mean Nusselt numbers. For the case of an infinitely-long tube, an explicit simple expression has been obtained, based on numerical results, to calculate the mean Nusselt number for the whole tube surface.
