Designing optical devices based on non-uniform rational Béziers splines

Teufel, Edgar - In: Renewable Energy 63 (2014) C, pp. 69-75

Optical system design has a significant impact on solar power plant efficiency. It can be advantageous to be able to very precisely adapt mirror shapes in order to improve energy yield. In this article it is investigated whether it is feasible to use non-uniform rational Béziers splines (NURBS)...

Optical performance of CPCs for concentrating solar radiation on flat receivers with a restricted incidence angle

Yu, Yamei; Liu, Nianyong; Tang, Runsheng - In: Renewable Energy 62 (2014) C, pp. 679-688

In some applications of compound parabolic concentrators (CPCs), the incidence angle of solar rays on the absorber is restricted and must be less than a specified value (θe) for efficient energy conversion or transfer. For a flat receiver with a restricted incidence angle (RWARIA, in short),...
