“…In the literature, different approaches of heat transfer in the case of moisture condensation from air can be found. For instance, Kazminejad et al (1993) and Chen (1991), analysing the heat transfer between moist air and a cooled surface, only considered the additional heat flux released due to condensation, while at the same time they neglected the influence of the condensate film.…”

“…For the case of low relative humidity, Kazeminejad et al (1993) assumed that the thermal resistance of the condensate film is negligible because the film is much thinner than the boundary layer in a dehumidification process. Their model showed that with increasing thickness of the boundary layer the heat transfer coefficient changed as well.…”

A three‐dimensional numerical analysis was carried out to study in detail the combined heat and mass transfer processes between a moist air flow and a cooled surface when film condensation occurs. A cross‐flow was considered between the air flow and the film flow. A turbulent flow was modelled using the Wilcox k−ω turbulence model. The shape of the interface between the air and the film was treated as a moving boundary, and it was calculated with the assumptions that the interface ways remain an interface, the stress at the interface is continuous and that there is no slip at the interface. Numerical results were obtained by solving simultaneous coupled equations of the air, film and solid. The results show that the condensate film flow has a significant effect on the extended surface temperature distribution and consequently on its efficiency. It is shown that the simultaneous influence of gravity and the air flow on the condensate film results in an asymmetric velocity profile in the film as well as in the asymmetric shape of the film.
