| 摘 要： | 结合集热器的光学特性,本文应用蒙特卡罗法对理想的槽型和碟型两种抛物面集热器在不同焦距、不同边缘角时焦面上的热流密度进行了计算,获得了焦距、边缘角和聚光比之间的关系。在考虑太阳不平行度、跟踪指向误差、镜面的反射误差条件下,对碟型抛物面太阳能聚能系统的辐射特性进行了数值模拟分析,获得了吸收器壁面热流分布以及边缘角对焦面热流分布的影响,为太阳能聚能系统的设计和安装提供参考依据。

| Abstract: | Coupling optical properties of solar collector, Monte Carlo method is employed to solve focal flux distribution in the ideal paraboloidal trough and dish concentrators in view of different focal lengths and run angles. The relationships between concentration ratio and focal length and rim angle are obtained. Considering the factors of unideal sunlight with angular diameter, tracking error and reflection error, radiation characteristics of paraboloidal dish solar collector system are computed and analyzed. So the distribution of wall flux in absorber and the effect of rim angle for focal flux distribution are obtained. The calculation results present a reference for the design and assemblage of the solar collector system. |
