Abstract: In this study, a corrugated solar air collector has been investigated experimentally to enhance the performance of conventional solar air collectors. Sets of experiments have been executed according to the standard ASHRAE tests, under climatic conditions in Najaf city in Iraq. The effect of the difference in air mass flow rate on thermal performance was studied for a corrugated solar air collector. The results reveal that the outlet air temperature decreases with increasing air mass flow rate which leads an increase in the thermal efficiency value as a result of low thermal losses to the atmosphere. The density of solar radiation and the appropriate climatic conditions of Najaf city makes the use of solar air collectors appropriate for reducing the use of fossil fuels and electricity consumption in many applications.
