Özet

In this study, the performance improvement of solar stills using different nanofluids was investigated analytically. Addition of CNTs to water (case 1), addition of Cu-Al2O3 nanoparticles (case 2) and addition of Al2O3-MWCNT-graphene nanoparticles (case 3) were considered. By using binary nanofluid, 26.67% more water was obtained compared to the traditional distiller. Similarly, a 24.41% energy efficiency and 33.32% increase in exergy efficiency was achieved. Outcomes is useful for selection of appropriate hybrid nanoparticles in nano-enhanced solar stills as hybrid nanofluids in energy systems is considered due to the cost, stability and synergistic impacts of individual nanoparticles on the overall performance.
