The present study examines the augmentation in heat transfer and friction in a flow through solar air heater duct with discretized broken V-rib roughness. The experimental outcomes pertaining to Reynolds number from 3000 to 17,000, relative gap position (s′/s) from 0.2 to 0.8, relative staggered rib position (p′/p) from 0.2 to 0.8 have been presented and discussed. Discretized broken V-rib roughness brought out considerable enhancement in heat transfer rates over V-rib roughness and smooth duct. Effective efficiency of discretized broken V-rib roughened solar air heater is estimated and geometrical parameters of roughness are optimized with regard to temperature rise parameter and insolation.

Abstract This study presents the geometrical optimization of a solar air heater. A reasonable working range of geometrical parameters: length 1–3 m, width 0.1–0.5 m, and height 0.005–0.05 m (or aspect ratio 1–20), is investigated as per general applications and installation constraints. The effect of these geometrical parameters on thermal (heat flux and outlet air temperature) and hydraulic (air velocity, mass flowrate, pressure loss and pumping power, and Bejan number) parameters are theoretically studied. Later, a numerical investigation is carried out with an optimum geometry of SAH-duct (length 2.44 mm and width 0.3 m), for aspect ratio 4–18 and Re 3000–15,000. An experimental study is also done to validate numerical results. The heat transfer and frictional loss do not show a significant change in the values for the aspect ratio 8–12.
