An experimental investigation has been carried out on heat transfer and friction characteristics by using square type protrusions as roughness geometry in the solar air heater duct Data have been generated for both the smooth as well as roughened absorber plate for fully turbulent flow in the range of system and operating parameters. Nusselt number and friction factor correlations have been developed by using the experimental data for predicting performance of the system having investigated type of roughness geometry.
