Study of hybrid nanofluids used in direct absorption solar collectors

Abstract The use of hybrid nanofluids in direct-absorption solar collectors is an efficient approach to harnessing energy. To address current energy challenges, this study new nanoparticle aggregates containing distinct silver-based and iron-oxide nanophases (Ag+Fe2O3) were used improve the photothermal conversion characteristics direct absorption collectors. main goal was investigate effect concentration efficiency on performance. Experimental results showed that increasing temperature nanofluid higher than base fluid, which means nanoparticles dispersed water have a stronger also indicated decreases as increases time or because heat loss through top surface sample at temperatures.
