| 摘 要： | 结合太阳能聚能器的光学特性,同时考虑了太阳不平行度、跟踪指向误差、镜面的反射误差以及焦面位置误差等误差因素,采用蒙特卡罗法对碟式抛物面太阳能聚能器的焦面特性进行了数值模拟分析,获得在等口径和等焦距条件下,边缘角对焦平面热流分布的影响,为碟式太阳能聚能器的设计和安装提供参考依据。

| Abstract: | The Monte-Carlo ray-tracing method was applied coupling with geometry optical properties.Some errors including unideal sunlight with angular diameter,tracking error,reflection error,alignment error were also included in this model.The effects of the rim angle of concentrator for flux distributions were showed in view of equal diameter and equal focal length in the paraboloidal dish concentrators.The calculation results present a reference for the design and assemblage of the solar collector system. |
