Laminar film condensation along a vertical fin

We study the conjugate condensation-heat conduction process of a saturated vapor in contact with a vertical fin, including both longitudinal and trans versal heat conduction effects. The momentum and energy balance equations a re reduced to a nonlinear system of partial differential equations with fou r parameters: the Prandtl number, Pr-c, Jakob number, Ja, a nondimensional fin thermal conductivity alpha and the aspect ratio of the plate epsilon. U sing the small Jakob limit and the boundary layer approximation, the total mass flow rate of condensed fluid has been obtained for all possible values of the involved parametric space.
