Energy and material saving considerations, as well as economic motivation have led towards developing an energy efficient solar air heater. in order to enhance the performance of the air heater, different turbulence generators such as ribs, baffles and delta winglets have been proposed. in this project work, a pin-fin based flat plate solar heater has been developed and compared its performance under two different configurations (configuration 1- without pin-fins and configuration 2 with pin-fins). the performance of the solar air heater has been evaluated under different climatic conditions of coimbatore city in india with different air mass flow rates. based on the performance comparisons, the air flow rate through the solar air heater is optimized.
