The study revealed that an increase in the concentration of alumina in the fly-ash nanofluid will increase the thermophysical property and efficiency of the nanofluid and an increase in the silica concentration will lead to decrease in the thermophysical property and efficiency of the fly ash-based nanofluid. Silica/fly ash (80:20)-based nanofluids achieved an exergy efficiency of 68.09%. This is significantly more than the silica/fly ash-based nanofluids. Exergy efficiency achieved by the alumina/fly ash (80:20)-based nanofluids is 73%. The experimental results revealed that the thermal efficiency of the alumina/fly ash (80:20)-based nanofluid for direct absorption solar collector is 72.82% while silica/fly ash (80:20) nanofluids showed 59.23% thermal efficiency. Experiments are conducted to evaluate the thermal efficiency, pumping power, performance evaluation criteria, entropy generation rate and exergy efficiency of fly ash-based nanofluids in direct absorption solar collector. Microchannel-based flat plate solar collector is used for the experimentation with a channel height of 800 microns. The effect of different proportions of major components in fly ash and flow rate on the thermal and exergy efficiency is studied. SiO 2, Fe 2O 3, Al 2O 3 and CaO are main components of the fly ash. In this study, the performance of the hybrid nanofluid of alumina/fly ash-based nanofluid and silica/fly ash-based nanofluid in the direct absorption solar collector is compared.
