Thermo-economic performance improvement of hemispherical solar still using wick material with V-corrugated basin and two different energy storage materials

Solar stills utilization has received great interest in arid isolated regions. In this study, experimental approaches have been investigated to prove the impact of the corrugated absorber shape on the hemispherical solar still performance. Four geometric corrugated shapes including present flat, triangular, semi-circular, square forms were tested for the corrugated absorber. Five hemispherical solar distillers have been fabricated and tested. The first distiller includes flat absorber (HSD-FA), the second distiller includes square corrugated absorber (HSDSA), the third distiller includes semi-circular corrugated absorber (HSD-SCA), the fourth distiller includes triangular corrugated absorber (HSDTA), and the fifth distiller is conventional (CHSD). The first and second distillers were compared with the CHSD on the first day. On the second day, the third and fourth distillers were compared with the CHSD as well. Experimental results obtained showed that, the total freshwater yield of the HSD-FA, HSDSA, HSDSCA and HSDTA were improved by 16.67, 27.08, 39.58 and 48.96%, respectively, compared over that of the CHSD. These results prove that the use of the triangular corrugated absorber shaped provides the highest thermal efficiency, and the optimum corrugated absorber shape is the triangular corrugated absorber shape.

NEOM is a proposed $500 billion smart city project planned to be built in Saudi Arabia. It aims to be a hub for innovation, sustainability, and quality of life, and will incorporate cutting-edge technology and renewable energy solutions. NEOM aims to transform the region into a hub for the future, attracting businesses and individuals from all over the world.. This article explores the potential application of solar still desalination in the NEOM region. Solar stills are a cost-effective and environmentally friendly solution for producing fresh water from saltwater sources. In the NEOM region, where access to fresh water is a major challenge, solar still desalination can play a significant role in meeting the growing demand for potable water. This research discusses the principles and components of solar stills, and the various types of solar stills that are currently available. This work also evaluates the performance and efficiency of solar stills, and their potential to provide large-scale water production in the NEOM region. Finally, the article highlights the potential benefits and challenges associated with implementing solar still desalination in the NEOM region, and provides recommendations for future research and development. This research contributes to the growing body of literature on sustainable water management, and has important implications for policymakers and water resource managers in the NEOM region and beyond.
