Utilization of zinc-ferrite/water hybrid nanofluids on thermal performance of a flat plate solar collector-a thermal modeling approach.

Thermodynamic performance analysis is carried out on a flat plate solar thermal collector utilizing single and hybrid nanofluids. FeO/water, Zn-FeO/water hybrid nanofluids, and water are used as heat transfer fluids, and their performance is compared based on the energy and exergy transfer rate. The thermo-physical properties are evaluated by regression polynomial model for all the working fluids.
