摘要
基于Matlab软件编程,以耐高温双干涉型W-Al_2O_3系太阳能吸收膜为例,采用正交实验方法,模拟研究W-Al_2O_3系高温太阳能吸收膜结构变化对其光学性能的影响规律,找出影响涂层光学性能的关键因素,经过膜系结构优化,获得吸收比达0.929、550℃发射比仅为0.075的涂层组合。
In the present work, a kind of high-temperature solar selective absorber coatings with a double cermet of W-Al2O3 was designed and simulated by programming based on Matlab software, orthogonal experiment approach was applied to analyze and optimize the structures of the coatings to achieve higher solar absorption and lower thermal emissivity. Variation of the metal volume fractions and thicknesses of the multi-layers on its optical properties were investigated to clarify the key factors in the coatings preparation. Finally, a combination of the solar selective coatings with absorptance of 0.929 and emittance at 550 ℃ of 0.075 was achieved.
