Effect of curved surface geometry on the productivity of solar distillation system: A review

Abstract

This paper carefully looks at how curved shapes affect the efficiency of making freshwater using solar distillation systems. It highlights the important role this has in renewable energy and water conservation. Solar distillation, harnessing the power of solar energy, emerges as a vital response to pressing global water scarcity issues by leveraging sustainable energy alternatives. This analysis accentuates the pivotal role of various curved geometries, including hemispherical, spherical, concave, and tubular shapes. These demonstrably enhance condensation surfaces and elevate productivity compared to conventional flat-surface distillers. Such innovative designs promote superior water yield by refining the interplay of heat and mass transfer phenomena. Empirical evidence substantiates that these curved geometries, in isolation from supplementary modifications, exhibit remarkable superiority over flat condensation surfaces, with productivity enhancements reaching notable levels and sometimes doubling the output. Moreover, incorporating sophisticated methodologies, such as integrating phase change materials, optimizing water basin designs, and applying nanotechnology, magnifies these advantages further. The ramifications of these technological advancements resonate profoundly, enhancing the efficiency and sustainability of desalination systems, thereby rendering them more feasible for combatting water scarcity in isolated and off-grid locales. The discourse presented within this paper synthesizes prevailing advancements, elucidates existing challenges, and delineates prospective research avenues within renewable water treatment technologies. Using clear and simple language helps everyone understand this study's importance, results, and wider effects for researchers and professionals.
