Abstract In this paper, the design process steps of a conventional solar parabolic trough with large rim angle are presented. The various parameters which intervene to obtain the suitable parabolic trough form of the concentrator are applied. Through an experimental characterization, the real focal distance and the focal zone size of the designed concentrator have been determined and compared with those calculated theoretically. Then, its concentration ratio is evaluated and the focused solar flux at the focal zone along the absorber tube is calculated using Soltrace code. It should be noted that the wind speed effect was not taken into account in the experimental tests which are conducted under a solar irradiation of 970 W/m2 and a receiver inclination angle of 36° which corresponds to the experimentation site latitude.

一种设计的大边缘角太阳抛物线槽的实验研究

摘要 本文介绍了传统大边缘角太阳抛物线槽的设计工艺步骤。应用干预以获得合适的抛物线槽形式的聚光器的各种参数。通过实验表征，确定了设计的聚光器的真实焦距和焦区尺寸，并与理论计算的值进行了比较。然后，评估其聚光比，并使用 Soltrace 代码计算沿吸收管聚焦区的聚焦太阳通量。需要说明的是，在 970 W/m2 的太阳辐照度和 36° 对应于试验地点纬度的接收器倾角下进行的实验测试中没有考虑风速效应。
