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 pressure drop. This article seeks to provide an overview of experimental research on the effects of ribs with various designs on fluid flow and heat transfer. It also outlines previously identified connections between the friction factor and the Nusselt number. To better understand the results of numerous studies on SAHs with different absorber surface roughness, a comparative evaluation of the literature was conducted. The aim of this work is to investigate the effects of artificial roughness on the duct’s heat transmission and friction properties.
