“…The condensation of vapor in a porous medium has received great interest in many theoretical and experimental researches [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Shekarriz and Plumb [1] analyzed the influence of the presence of the porous medium on the condensation of a film on the external wall of a horizontal tube.…”

The forced convection thin film type condensation of pure saturated vapor in a channel whose walls are covered with a porous material is studied numerically. To describe the flow, in the porous medium the generalized model of Darcy-Brinkman-Forchheimer (DBF) is used while the classical equations of the boundary layer have been exploited in pure liquid. These equations thus rendered dimensionless, are solved by an implicit finite difference method and the iterative Gauss-Seidel sub-relaxation method. We note that an increase in the ratio of form (or length of the cold plate) allows better contact with the cold plate, increases the friction imposed by this porous wall and allows a decrease in velocity and temperatures in the porous medium and the pure liquid. It also causes an increase in the thickness of the liquid film (favored condensation), decreases the rate of heat transfer at the porous medium / liquid film interface and the lengths of entry. This decrease in lengths of entry is exponential and very significant when the ratio of form is between 55 and 100 (55≤L/A≤100). We conclude that the sensitivity of condensation to a change in ratio of form is very high between 55 and 100.
