Abstract |
This paper deals with the thermal analysis of the artificially roughened duct of a solar air heater duct in the form of V shaped ribs and arc shaped ribs. The absorber plate of the solar air heater is roughened to enhance the heat transfer coefficient by providing turbulence. In this paper a thermal analysis of various type rib geometry used as turbulent promoters is done by determining the Nusselt number and friction factor of solar air heater duct. It is found that multiple V ribs with gaps give the maximum heat transfer rate as well as thermal performance. Keywords - Solar air heater, V ribs, Arc shape ribs, Thermal performance. | |||||||||
