Effects of Froude, Reynolds and Prandtl numbers on the thermal field

Abstract

A numerical study of the condensation in forced convection of a pure and saturated vapor on a vertical wall covered with a porous material is presented. The transfers in the porous medium and the liquid film are described respectively by the Darcy-Brinkman model and the classical boundary layer equations. The dimensionless equations are solved by an implicit finite difference method and the iterative method of Gauss Seidel. We analyze the influence of Froude, Reynolds and Prandtl numbers on the thermal fields in the liquid phase and the porous medium. The results of this study show that the Froude, Reynolds and Prandtl numbers have no influence on the thermal field.
