| 摘 要： | 采用蒙特卡洛射线踪迹法，ProE和TracePro软件技术，模拟分析了多棱台与一次抛物面、复合抛物面二次聚集器与一次抛物面两级聚集器的太阳光聚集传输特性。通过对比，发现多棱台二次聚集器的几何聚光比为1.4左右(约为复合抛物面聚集器的70%)。多棱台与一次抛物面、复合抛物面二次聚集器与一次抛物面两级聚集器圆筒侧壁和底面的太阳能流密度分布图像相当(沿圆周方向，复合抛物面两级聚集器相对比较平滑)。结论为反射二次聚集器技术发展提供理论依据。

| Abstract: | Monte Carlo ray tracing method, ProE and TracePro software technology were used to simulate and analyze the solar light gathering and transmission characteristics of the polygonal prism and the primary parabolic surface, and those of the compound parabolic secondary concentrator and the two-stage primary parabolic concentrator. Through comparison, it was found that the geometric concentration ratio of the two-stage polygonal prism concentrator is about 1.4 (about 70% of the composite parabolic concentrator). The solar energy flow density distribution image on the cylinder side wall and the bottom surface of the polygonal prism and the primary parabolic surface is equivalent to that of the composite parabolic secondary concentrator and the primary parabolic two-stage concentrator (along the circumference direction, the composite parabolic two-stage concentrator is relatively smoother). The conclusion provides a theoretical basis for the development of reflective two-stage concentrator technology. |
