Summary

In this study, the thermal properties of a dish solar collector using Fe3O4 nanofluid were investigated through surface response analysis to optimize design. The independent variables included Fe3O4 nanofluid concentration, collector height, spiral number, and emissivity, and the independent variables affected thermal efficiency in the following order: Fe3O4 nanofluid concentration (11.59) > emissivity (7.24) > height (5.38) > spiral number. It has been confirmed that the concentration of Fe3O4 nanofluid, which is the independent variable with the greatest influence, can significantly improve thermal efficiency by increasing light absorption as it increases. The next significant factor is the emissivity of the receiver, which enables high thermal efficiency even at low Fe3O4 nanofluid concentrations. However, if both the concentration of Fe3O4 nanofluid and emissivity are high, it may lead to radiant heat loss to the surroundings, which could suppress the enhancement of thermal efficiency.
