基于自由曲面的聚焦型太阳模拟器设计
Design of focusing solar simulator based on free-form surface
摘要
Abstract
The concentrating solar simulator can obtain solar radiation spots with high-power convergence,which has important applications in the fields of solar thermal power generation and thermochemical re-search.To obtain uniform solar radiation spots,a free-form surface condenser design method based on non-imaging optics is proposed,and its design principle and specific method are described.The designed free-form condenser is compared with a non-coaxial ellipsoidal condenser with the same containment angle,and the correctness of its design method is verified by simulation analysis.The simulation results show that when a xenon lamp with a rated power of 6 kW is used as the light source,the single-lamp solar simulator com-posed of a free-form condenser can produce a spot with an average irradiance of 274.4 kW/m2 in the target region with a diameter of 60 mm.The spot's unevenness decreases from 18.28％to 5.69％compared with that of a non-coaxial ellipsoidal solar simulator.The seven-lamp solar simulator can produce a spot with an average irradiance of 1.65 MW/m2,with a spot unevenness that decreases from 13.19％to 5.49％.关键词
