Abstract

Laminar film condensation of a saturated vapor in forced flow over a flat plate is analysed. The problem is formulated as an exact boundary-layer solution. From numerical solutions of the governing equations, it is found that the energy transfer by convection is negligibly small for low Prandtl number liquids (liquid metals) but quite important for high Prandtl number liquids. The condensation rate, skin friction and heat transfer are presented in graphs as a function of c p ΔT/ Prh fg with [(ρμ)L/(ρμ) ν] 1 2 and Pr as parameters.
