Transformative nanofluid solutions: Elevating solar still performance for enhanced output

Abstract

Population expansion is placing more and more pressure on the world’s water supplies, which emphasizes the need of renewable energy sources, especially solar desalination. Because of their environmental advantages and dependability, solar stills are one type of solar desalination device that is attracting the attention of researchers. Still, there are problems with solar stills’ efficiency. Modern solar research has shown a great deal of interest in the developing subject of nanofluids due to its remarkable qualities and distinctive features. This study investigates the use of nanofluids in solar distillation, emphasizing the optimization of their form, optical characteristics, and thermal properties. The bulk of the research in this study, which looks at the effect of nanofluids on solar still efficiency both with and without their inclusion, is from the last ten years. The goal of the project is to improve heat transfer between absorber plates and saline water by improving the physical characteristics of nanofluids. It also explores the quantum characteristics of nanofluids in solar desalination, emphasizing their capacity for absorption. Heat transfer and overall performance of the solar still are significantly improved by adding metal oxide-based nanofluids to the working fluid. Applications of solar stills to comprehend the effects of nanofluid characteristics, such as particle size, shape, and particular sun absorption zones, are also covered in the study. There are several preparation methods for evaluating the stability of nanofluids. Under key headings, the effects of various nanofluid types on solar still performance are examined. The research showed that when Cu2O nanofluid was used at a concentration of 1.95 %, the yield increase over conventional solar stills was the greatest, at 279.6 %. The introduction of a sustainable environmental controller specifically designed for solar stills highlights its function in reducing pollution while purifying water. The work emphasizes how important it is to employ nanofluid structures in order to improve internal heat transfer processes. It also emphasizes how crucial it is to put marketing plans into action to draw attention to the important role that nanofluids in solar stills play in providing solutions to global problems and influencing the course of future research in this area. Complete tables with further resources are included with the results.
