Investigation Enhancement of Solar Still by Analysis Heat Transfer with Fresnel Lens and Phase Change Materials

Abstract

One of the major issues facing the globe today is the lack of access to clean drinking water. Due to causes like population expansion, industrialization, urbanization, etc., water contamination significantly rises. Desalination has occasionally seen the development of a number of innovative methods, while solar distillation is thought to be more cost-effective. In this study, a steps distillation basin slope single basin solar still was used to examine the effect discusses the transformation of salt water into drinkable water by the Fresnel lens. When distillers were used with phase change materials, the temperature increased than it was without phase change materials, by increasing the working hours of the distillers, and thus increased productivity. But when distillers were used with phase change materials and a Fresnel lens, the productivity increased than it was due to the increase in temperature, as well as increased evaporation of water, as well as increased work The distiller works at night due to the presence of phase change materials, and thus the productivity of the distiller increased than it was before the lenses were placed. The outcomes demonstrate that the employment of Fresnel lenses and phase change materials can successfully transform salt water into drinking water.
