Arrangement and Shape Optimization of Solar Concentrating Receivers Using Monte Carlo Method
Uniform radiation flux distribution in the received surface is crucial for the performance and conversion efficiency of a solar concentrating system. In order to improve the uniformity of radiation flux distribution in the receiving surface, the arrangement and shape optimization of solar concentrating receivers is proposed. Considering the sun shape, the radiation flux distribution is determined by Monte Carlo ray-tracing method, and an optimization model is established, which takes the receiver aperture size as the constraint condition and aims at the highest uniformity of radiation flux distribution combing Kiefer-Wolfowitz algorithm. We take a linear parabolic-trough concentrating system for example, resulting in the most uniform intensity distribution while achieving a high energy reception of 78.25%, which testifies the validity of this optimization procedure. The optimization procedure computes more efficiently than the traditional trial-and-error methodology, and the obtained solutions are also near optimal.
