Abstract

The evolution of nanofluids over the years has opened new research opportunities in the field of renewable energy. Research on the optical properties of nanofluids for application in direct absorption solar collectors (DASCs) is progressing at a burgeoning speed. In a DASC system, nanofluid with high optical absorptivity can convert the incident solar energy into the thermal energy of the fluid. The dispersed nanoparticles in the fluid act in the process through the phenomenon of absorption and scattering. Studies conducted on the optical property characterization of monocomponent nanofluids have become saturated. Moreover, the photothermal efficiency (PTE) of the nanofluid can be enhanced by using multicomponent nanofluids. Nanofluids prepared using varying materials, shapes and sizes of nanoparticles can tune the absorption spectra of the bulk fluid to improve the PTE. A hybrid nanocomposite can similarly enhance the absorptivity due to the synergy of materials present in the nanocomposite particle. In this review, a comprehensive survey on the synthesis and optical characterization of different monocomponent, blended and hybrid nanocomposite nanofluids has been performed.
宽带吸收单、混合和混合纳米流体的直接吸收太阳能集热器:综合综述
近年来纳米流体的发展为可再生能源领域开辟了新的研究机遇。用于直接吸收太阳能集热器(DASCs)的纳米流体光学性质的研究进展迅速。在DASC系统中,具有高光吸收率的纳米流体可以将入射的太阳能转化为流体的热能。分散在流体中的纳米颗粒通过吸收和散射现象在此过程中起作用。对单组分纳米流体光学性质表征的研究已经趋于饱和。此外,多组分纳米流体可以提高纳米流体的光热效率(PTE)。使用不同材料、形状和大小的纳米颗粒制备的纳米流体可以调整体积流体的吸收光谱,从而改善PTE。由于纳米复合材料颗粒中存在的材料协同作用,混合纳米复合材料也可以类似地提高吸收率。本文综述了单组分、共混和杂化纳米复合材料纳米流体的合成及其光学特性。
