Performance Investigation of a Solar Thermal Collector Based on Nanostructured Energy Materials

The convective and conductive heat transfer between the solar collector working fluids make photothermal performance limited, result in a higher rate of loss from surface conventional absorber to surroundings. Direct absorption collectors (DASC) are favorable alternative for their improved performance. In this study, simulation based on nanostructured has been carried out using TRNSYS. connective direct were by nanofluids three different materials, CuO, GO, ZnO, study. analysis determines outlet temperature that passed through collector. TRNSYS model consists weather Lahore city, simulations performed whole year 1,440 h. stability these materials water was investigated UV?Vis spectrophotometer. Various parameters determined, such as variation rates. numerical is validated with experimental results. A maximum 63°C observed GO-based nanofluids. results show year, collectors. Significant improvements 23.52, 21.11, 15.09% nanostructures GO respectively, compared water. These energy beneficial solar-driven applications like desalination, water, space heating.
