Simulation Study on the Efficiency of Flat Plate Solar Air Collector with Baffles

Marwa Ammar, Ameni Mokni, Hatem Mhiri


Abstract—In the present paper, we present a simulative study to evaluate the effective and exergy efficiency of a flat plate solar air collector with baffles. We have carried out a Fluent simulations incorporating the operating and system parameters. The variation in air flow rate with reference to the design parameters of the baffles is presented. A various number of baffles are studied. Solid and perforated baffles are also investigated. Eight solid and perforated baffles produce an effective efficiency of 62%, 60% respectively, and a pump power of 7.9%, 3.5% respectively for a volume flow of 85.33m3 /hm2 . Results reveals that; the collector with eight perforated baffles represents the best design in term of high performance, lowest pump power consumption and lightness of the collector. Index Terms—Solar air collector, Rectangular baffles, Effective efficiency, Exergy efficiency, Serpentine flow.
