Paper Title - Thermal Analysis of V Shape Rib Roughness on a Solar Air Heater Duct
This paper deals with the comparative study of the artificially roughened duct of a solar air heater duct in the form
of V 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.
