Краткое описание

The laminar film liquid condensation saturated in a porous medium is studied by using Forchheimer models, with and without shear stress. The models are based on the classical analysis carried out by Nusselt. For both models, the closed form expression is obtained for film thickness condensate, mass flow rate, convection heat transfer coefficient, local and average Nusselt number. The results show different dimensionless film thickness for liquid and vapor layers, different velocity profiles, temperature profiles and Nusselt number, and show the effect of Grashof number and shear stress on the outer edge of liquid layer on the film thickness layer.
