Abstract

Thermal performance of a low cost linear Fresnel solar collector with an absorber tube and a secondary reflector has been studied. The design was made with a compact geometry with optimum optical efficiency. The focal point was determined through iterative methods. The absorber characteristics were studied to determine the best factors that can improve efficiency of the system. The black coated absorber was investigated to achieve better heat gain and efficiency. The increase in heat transfer, fluid flow rate improves the thermal efficiency. Further, the overall efficiency of the system is increased by implementing a secondary reflector by 10%.
