| 摘 要： | 对大型对日定向的碟式太阳能反射聚集器,通过数值模拟研究了太阳光不平行度与定向跟踪精度对聚光性能的影响。通过建立锥形光束的概率模型,采用蒙特卡洛法直接模拟了太阳光经碟式反射聚集器后在焦平面上产生的能流分布。比较了不同定向跟踪精度下,不同口径比的反射聚集器对太阳光与平行光的聚集性能差别。

| Abstract: | For a large dish-shaped reflect concentrator directionally tracking the sun,the effects of non-parallelism of solar rays and the of the directional tracking precision of reflectors on the concentrating capability were investigated numerically.Based on the probability model derived from the solar cone,the energy flux distribution the propagation of solar rays on the focal plane was directly simulated by the Monte Carlo method.The concentrating concentrating capabilities of the reflect concentrators with various aperture ratio and the directional tracking precisions for the solar rays was compared with that for the collimated beams. |
