        abstract = {Applications of artificial roughness on the underside of absorber plate in solar air heater duct have been widely used to improve heat transfer with moderate increase of friction factor. The design of the roughness shape and arrangement is most important to optimize the roughened surfaces.
	A Finite Element Analysis of artificial roughness geometry of V rib type in the absorber plate of solar air heater duct has been carried out and compared with smooth duct. A comparative Finite element analysis has been carried out for air at different velocity (inlet) and temperature of fluid for both absorber plate surfaces. The outcomes of the present Finite Element analysis represents the artificial roughened surface is more suitable then the flat plate surface solar air heater. 
The objective of the present study is to review on the comparative study of flat surface solar air heater with an artificially roughened surface solar air heater on the basis of various conditions like as,Varying fluid inlet temperature, Varying fluid inlet velocity},
