Construction method and optical characterization of parabolic solar modules for concentration systems

Treatment of surfactant-rich industrial wastewaters with concentrated sunlight: toward solar wastewater remediation

“…The spectral profile of the concentrated light is reported in Fig. S1, supplementary information, while an extensive characterization is reported elsewhere (Eccher et al 2013). Note that while a portion of UV photons (λ < 330 nm) is lost with respect to sunlight (see inset Fig.…”

Solar Concentration for Wastewaters Remediation: A Review of Materials and Technologies

“…Figure 3 presents a schematic drawing and an image of a parabolic module in use in our laboratories. This collector is based on an innovative process to manufacture parabolic mirrors, resulting in potentially very low production costs [52,53]. Several CPC type configurations have been realized and tested by companies such as AO SOL and Energias Renováveis Lda, and have been central to recent research efforts such as Project CADOX, Almeria, Spain [46,47].…”

In solar wastewater purification, the selection of a PDC is motivated by specific needs.…”

Research on Thermal-Sthuctural-Optical Multi-field Coupling Modeling and Concentrating Performance Predication of Solar Dish System

“…采用光 线跟踪方法建立了空间碟式聚光器的焦平面能流分 布模型，考虑了面形误差和跟踪误差。李瑞恒等 [2] 在考虑面形误差和跟踪误差等，采用有限微元积分 方法建立了聚光器焦平面能流分布模型。杜胜华 等 [3] 分析了太阳光不平行度和跟踪误差对焦平面能 流分布的影响。王云峰等 [4] 分析了采光口形状几何 参数对聚焦能流分布的影响，并考虑了接收器的遮 挡作用。成珂等 [5] 研究了反射镜面形误差对聚光性 能的影响，并指出切向角微小误差将导致聚光性能 量级的变化。LEE [6] 则更为系统地分析了表面斜率 误 差 对 聚 光 性 能 的 影 响 。 在 试 验 研 究 方 面 ， LOVEGROVE 等 [7] 研制了多镜面单元拼合的大型 碟式聚光器(采光面积为 500 m 2 )，并进行了焦平面 能流分布的试验研究。ECCHER 等 [8] 研制了辐射状 单元的模块化碟式聚光器，并开展了焦平面能流分 布试验研究，指出了面形误差影响光学效率但可通 过反射镜材料或工艺得到改善。但就目前公开文献 来看，碟式聚光模型主要是考虑面形误差和跟踪误 差等方面，对几何形状误差的考虑仍是少见，仅文 献 [9]引入了平面接收器的安装误差，以及文献 [10] 考虑了镜面单元安装误差对镜面法线矢量的影响。 同时以往能流分布建模的接收器也多为平面或基于 理想聚光的腔式接收器 [11][12][13] 。然而，大型聚光器采 …”
