Numerical study of light reflection absorption affected by sinusoidal-corrugated solar air collector

The influences on the absorption rate with different slope of incident light and aspect ratio are presented. The results show that the effect of aspect ratio on the absorption rate is larger, while the slope of incident light is relatively smaller. The results of the present work imply that the rational aspect ratio is 1. According to this conclusion, the optical path of sinusoidal-corrugated solar air collector with aspect ratio 0.5, 1 and 1.5 is simulated respectively by TRACEPRO software using. The conclusion is also verified by the simulations.
