Abstract


A numerical study of the forced condensation in a pure saturated steam and to a vertical wall covered with a porous material are brought convection. The transfer in the liquid medium and the porous film are disclosed respectively by the Darcy-Brinkman model and conventional equations for the boundary layer. The dimensionless equations are solved by an implicit finite difference method combined with an iterative method like Gauss-Seidel. The film thickness of the condensate is determined from the heat balance equation of the liquid vapor interface is solved by an iterative procedure. We analyze the influence of Reynolds and Jacob numbers, the dimensionless thickness of the porous layer and the non-dimensional thermal conductivity transfers in the liquid phase
