Abstract

Turbulent flow and convective heat transfer of air inside channel of rectangular cross-section, containing rectangular baffles with inclined upper part planted on the opposite surface of absorber plate is investigated numerically under solar air heater boundary conditions. For a fixed value of heat flux (1000 W/m2) and the range of Reynolds number from 4000 to 18,000, the effect of four baffle blockage ratios, (BR = 0.7, 0.82, 0.92, 0.98) and four baffle-pitch spacing ratios, (PR = 2, 4, 6, 8) in sixteen configurations on thermohydraulic behavior were confirmed.
