✦ Synopsis

Hydrodynamic characteristics of liquid films in downward motion on the outer surface of fluted tubes have been inuestigated theoretically. Velocity distribution, volumetric flow rate and friction factor are calculated from the solution of the equation of motion using bi-polar coordinate system. The results provide sufficient information pertaining to the thickness of the condensate film and its variation, thus enabling the prediction of heat transfer coefficients in desalination.

Film condensation of stagnant water vapor on both vertical and horizontal spir~ly fluted robes was studied theoretically. A sine flute was taken as a typical example. In the analysis two regions of the flute, namely the valley and the crest, are treated separately. The condensation process takes pla
