This study has examined and reported heat transfer analyses in flat plate solar collectors (FPSC) based on nanofluids. For the purpose, theoretical modeling and simulation are used. Al2O3-H2O nanofluid in the absorber tubes of the collector has been taken into consideration. The amount of heat lost from the absorber plate to the surrounding air is estimated using an overall heat loss coefficient. Before a parametric analysis involving the effects of mass flow rate, inlet temperature, wind speed, and solar radiation is estimated, the influence of the percentage of volume fraction of nanoparticles is first investigated. In comparison to water, it is discovered that the addition of nanofluid only slightly improves heat transfer.
