Abstract
This paper presents an experimental exergy analysis for a flat plate solar air heater (SAH) with shot peenned artificial roughness and without obstacles (smooth plate). For increasing the available heat-transfer area may be achieved if air is flowing over roughened absorbing plate, instead of smooth plate, leading to improved collector efficiency. The measured parameters were the inlet and outlet temperatures, the absorbing plate temperatures, the ambient temperature. Further, the measurements were performed at different values of mass flow rate of air. The results show that the largest irreversibility is occurring at the flat plate (without obstacles) collector in which collector efficiency is smallest.
