Abstract

This study aims at improving the thermal analysis of a semi-cylindrical, stepped-basins solar still (SCSBSS) that incorporated with (PCM-Paraffin-wax) phase change material. The SCSBSS was evaluated and compared with the semi-cylindrical solar still (SCSS) as a conventional one under various water depths for Egyptian climate conditions for different salt water quantities. Furthermore, the economic analysis, energy and exergy efficiencies for various modifications were discussed. The results show that the best performance belongs to the SCSBSS with PCM which produced 3889 mL/m2.day with an increase of the daily productivity of 44.52 % compared with SCSS without using PCM at salt water quantity of 20 L. The CPL of potable water and payback period for a SCSBSS with PCM were approximately 0.0157US$/L and 123 days with a considered lifespan of 10 years at salt water quantity of 20 L. In addition, the results indicated that the thermal and exergy efficiencies of SCSBSS with PCM were 36.86 % and 3.27 % respectively.

研究集成了阶梯式盆地和相变材料的半圆柱形太阳能蒸发器的经济、能量和能效问题

本研究旨在改进加入（PCM-石蜡）相变材料的半圆柱形阶梯式盆地太阳能蒸发器（SCSBSS）的热分析。在埃及气候条件下，在不同水深、不同盐水量的条件下，对半圆柱形阶梯式盆地太阳能蒸发器（SCSBSS）进行了评估，并与传统的半圆柱形太阳能蒸发器（SCSS）进行了比较。此外，还讨论了各种改造的经济分析、能效和放能效。结果表明，在盐水量为 20 升时，使用 PCM 的 SCSBSS 性能最好，日产量为 3889 毫升/平方米，与不使用 PCM 的 SCSS 相比，日产量提高了 44.52%。含 PCM 的 SCSBSS 的饮用水 CPL 和投资回收期分别约为 0.0157 美元/升和 123 天，盐水量为 20 升时的使用寿命为 10 年。此外，研究结果表明，含 PCM 的 SCSBSS 的热效率和放能效率分别为 36.86 % 和 3.27 %。

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
