摘要

太阳能仍然是解决水资源短缺的一种有前途的环保解决方案,但其效率仍然有限。本研究旨在通过提高蒸馏水生产率和降低生产成本来改善斜栅式太阳能蒸馏器的热学和经济性能。本研究的新颖之处在于两个设计参数的优化,即吸收板中挡板的数量和绝缘厚度,这两个参数在文献中尚未研究过。通过基于中心复合设计的参数敏感性分析,利用CFD模型评估了这些参数对系统性能的影响。采用响应面法(RSM)和非支配排序遗传算法(NSGA-II)相结合的多目标优化方法,利用9个数值经验的模拟结果确定最优值。优化结果表明,保温厚度为100 mm和在吸收板上放置10个挡板提供了最佳折衷方案,实现了11.58 kg/m2的日生产率和0.0088美元/kg的蒸馏水成本。这些结果证实了优化的倾斜级联太阳能蒸馏器在生产低成本淡水方面的潜力,并强调了其在实施可持续解决方案方面的实际意义,特别是适用于面临日益短缺饮用水的干旱地区。

Multi-objective optimization of an inclined cascade solar still for enhanced thermal and economic performance
A solar still is a promising and eco-friendly solution to address water scarcity, but its efficiency remains limited. This research aims to improve the thermal and economic performance of an inclined cascade solar still by increasing distilled water productivity and reducing production cost. The novelty of this study lies in the optimization of two design parameters, the number of baffles in the absorber plate and the insulation thickness, which have not yet been investigated in the literature. A parametric sensitivity analysis based on a Central Composite Design and used a CFD Model was conducted to evaluate the effect of these parameters on system performance. Simulations results of nine numerical experiences are then exploited to determine the optimal values using a multi-objective optimization approach combining Response Surface Methodology (RSM) and the Non-dominated Sorting Genetic Algorithm II (NSGA-II). The optimization results show that an insulation thickness of 100 mm and the10 baffles placed in the absorber plate provide the best compromise, achieving a daily productivity of 11.58 kg/m2d and a distilled water cost of 0.0088 $/kg. These results confirm the potential of an optimized inclined cascade solar still to produce low-cost fresh water and highlight its practical implications for implementing sustainable solutions, particularly suited for arid regions facing an increasing scarcity of drinking water.
