摘要(Abstract)：

通过数值模拟的方法为槽式太阳能聚焦集热器选取一种最佳的太阳跟踪方式,具体研究内容包括:地表日太阳直射辐射量的计算、不同太阳跟踪方式时槽式太阳能聚焦集热器的抛物面反射镜年接收太阳直射辐射总量的对比,以及南北倾斜式跟踪方式最佳倾角的研究。研究发现,在上海地区,槽式太阳能聚焦集热器的抛物面反射镜接收的太阳直射辐射量从高到低排序时所采用的太阳跟踪方式依次为:双轴>南北地轴式>南北倾斜式(倾角β=15°)>南北倾斜式(β=45°)>南北水平式>东西水平式。研究结果表明,单轴跟踪方式的系统结构简单,成本较低;1年中有7个月采用南北倾斜式跟踪方式时,槽式太阳能聚焦集热器的抛物面反射镜接收的太阳直射辐射量大于采用南北地轴式跟踪方式时接收的太阳直射辐射量,因此,对南北倾斜式跟踪方式进行了单独研究,确定了南北倾斜式跟踪方式在海口市、拉萨市、上海市、北京市和呼和浩特市5个地区的最佳倾角分别为18.81°、27.29°、28.67°、36.21°和37.97°。
