A detailed mathematical model is modified that describes heat and mass transfer through Combined Compact Evaporative Cooler CCEC using mono-scale sintered particles coating. The model accounts for the effects of particles size, Reynold’s number, and channel spacing on system performance for certain operating conditions. In this study, a Kelvin-Clapeyron equation is utilized to obtain numerical data for an evaporating meniscus in the wet channels and compared to the plain surface. The results indicate that porous coatings enhanced evaporative heat and mass transfer in the wet channels significantly, compared to the plain wet channels walls, due to wicking water that covers entire heated surfaces.
