ABSTRACT
The two most important processes that drive dew water condensation, heat transfer and radiative cooling, can be simulated by computational fluid dynamics. Computational fluid dynamics can give access to all instantaneous information for each point of the field of calculation, with generally modest overall costs as compared to field experiments. Ideally, both processes of cooling and condensing should be considered. However, calculating the condensing water is a problem much more complicated than obtaining the cooling temperature. A radiative module can be activated as was the case in the study by Sharan et al. who used the COMSOL commercial code. The correction for thermal conductivity is isotropic and thus increases the heat flux components parallel to the condenser surface. Mean cooling of such positive cones and pines seems inferior to a suitably oriented and tilted planar structure. Symmetrical structures such as hollow cones also prevent wind effect but are in addition insensitive to wind direction.
