Abstract:Considered the liquid transverse suction effect at the porous layer interface, mathematical models was presented to investigate the influences 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 comparising the thermal resistances within the external condensate film and the porous layer.
