EXPERIMENTAL INVESTIGATION OF FLAT PLATE COLLECTOR WITH CYLINDRICAL FINS IN A SOLAR AIR HEATER
The main objective of this work is to increase the efficiency of solar air heater (SAH). The efficiency of SAH is increased with increasing the rate of heat transfer. The rate of heat transfer can be increased by increasing the surface area by cylindrical fins. The cylindrical fins are arranged tangent to the absorber plate. The flat plate solar air heater with and without cylindrical fins on the absorber plate is constructed and tested for five different mass flow rates of air. From the experimental results, optimum mass flow rate is found for maximum collector efficiency.
