In a compound parabolic solar collector, a glass cover is normally used for decreasing the rate of heat loss from the absorber. In this paper, a solar collector with two glass covers and a concentration ratio of 1.6 is simulated and examined for the purpose of higher performance. The distance between covers is 45 mm and the cavity of solar collecto...

The main contribution of this study is to present a modified V-corrugated grooved absorber plate in the construction of plane solar air heaters for higher performance. The combined effects of extended heat transfer area due to the V-shaped absorber, the suction process by the grooves that maintains the convective flow closed to the heated absorber ...
