Thermo-Hydraulic Performance of Solar Air Collectors With Artificially Roughened Absorbers: A Comparative Review of Semi-Empirical Models
Due to the poor thermal characteristics of the air, the absorber roughness of solar air collectors is commonly artificially increased in order to enhance the heat transfer to the air stream. However, this is also accompanied by an undesirable increase in the pumping power due to increased friction l...
