摘要: 以用于线性菲涅尔式聚光系统的CPC为研究对象,在Matlab环境下建立了数学模型。利用光线跟踪法对不同间隙、不同最大接受半角和不同截取比的CPC汇聚率进行仿真研究,结果表明用于线性菲涅尔式聚光系统的CPC对不同入射角光线具有特定的汇聚率,随着入射角的变化会出现极小值,极小值所对应的入射角仅与CPC最大接收半角相关,与截取比和间隙无关。仿真计算了间隙为50 mm、最大接受半角为45、截取比为0.75的CPC汇聚率为80.15%。最后通过实验验证了仿真方法的有效性。

Abstract: Compound parabolic collector (CPC) plays an important role in optical efficiency of linear Fresnel reflector (LFR) system. The CPC for LFR was studied, and its mathematical model was established by using Matlab. The method of ray tracking was used to calculate the convergence ratios of CPC with different gap, different maximum acceptance angle, and different truncation ratio. The simulation study illustrates that the CPC for LFR has the specific convergence ratio for the ray with different incident angle. There are two minimum points in the convergence ratio with the change of incident angle. And their positions only depend on maximum acceptance angle, not including truncation ratio and gap. The CPC with gap 50 mm, maximum acceptance angle 45, and truncation ration 0.75, could achieve a high concentrate ration about 80.15%. The simulation method was further verified by the experimental measurement results, and it has guiding significance for design of CPC.
