Review of the Impact of Artificial Roughness in Solar Air Heaters
Abstract: Artificially roughening the heated surface of solar air heaters is a practical and affordable method to significantly increase the rate of heat transmission. Roughing up the surface can improve the design of a solar air heater (SAH) duct. The use of baffles, fins, ribs and grooves improves heat transmission in the SAH. Various efforts were made to improve heat transfer rates through duct employing these components, which resulted in significant …
