“…Recently, a series of reports published by Renken's group [6][7][8][9] presented further experimental and modeling works on condensation heat transfer with a porous coating. Ma and Wang [10] investigated the same problem by considering the condensate stress force at the interface of the porous layer and the external condensate film. Actually, Notar [11] found early that a 6.0-m-long vertical tube with a 50% area density of 0.5-mm-diameter particles yielded a stem condensation heat transfer coefficient 17 times that predicted by the Nusselt equation for an equal-length tube.…”

Considering the liquid transverse suction effect at the porous layer interface, a mathematical model was presented to investigate the influence of the porous layer characteristic parameters on condensation heat transfer. The results revealed that the enhancement ratio increased with the increase of the porous layer thickness and permeability. The effective thermal conductivity of the porous layer was, however, of little significance for condensation heat transfer enhancement. Also, the enhancement mechanism was analyzed by comparing the thermal resistances within the external condensate film and the porous layer.

“…Xuehu Ma et al [11] extend their work to the case of film condensation on a vertical porous coated plate is investigated numerically for a porous/fluid composite system based on the dispersion effect in the porous coating. The mathematical model improves the conventional matching conditions by considering the stress force at the porous coating interface.…”

The author found from the equation of local energy balance differential relation between the thickness of the condensate, the longitudinal abscissa and the different physical parameters of the problem. We numerically integrate the equation for the thickness of the liquid layer by the Runge-Kutta fourth order analysis and influence the physical and geometrical parameters of its variations. We will examine the influences of the dimensionless thermal conductivity λ*, certain characteristic numbers (Peclet (Pe) and Jacob (Ja) numbers) and geometric (dimensionless thickness of the porous layer H*) on the profiles of the thickness dimensionless liquid film.
