摘要
本文使用蒙特卡洛方法对新型轮胎面太阳能聚能器的焦面特性进行了数值模拟计算,计算了当入射面积增大时焦平面处的热流分布变化,之后计算了考虑太阳不平行度时,在不同的镜面指向误差、系统跟踪误差等因素的影响下,接收面积为1 m×1 m的聚能器在其焦平面处的热流分布变化。
The Monte-Carlo ray-tracing method was applied in studying the characteristics of focal plane of a new heliostat which was a toroidal mirror. Some errors such as unideal sunlight with angular diameter, tracking error, reflection error, alignment error were also calculated in this model. We compared the collecting ability with different receiving areas of this new heliostat and the effects of the errors for flux distributions on the focal plane were showed when the receiving area of the heliostat was 1 m×1 m.
