| 摘 要： | 基于蒙特卡洛方法建立光线追踪模型，利用CCD相机和朗伯板展开聚光实验，实验结果表明测量光斑与模拟光斑在大小、形状和能量分布上吻合良好。针对腔体吸热器提出光热耦合模型，考虑腔内不同吸热管之间的辐射换热，模拟结果与实验结果最大相对误差为8.6%。

| Abstract: | A ray tracing model is established based on the Monte Carlo method, and a CCD camera and a Lambertian plate are used to carry out the concentrated flux experiment. The experimental results show that the measured and the simulated spots are in good agreement in size, shape and flux distribution. A photothermal coupling model is proposed for the cavity receiver. Considering the radiation heat transfer between different heat absorbing tubes in the cavity, the maximum relative error between the simulation results and the experimental results is 8.6%. |
