Abstract

This study experimentally investigates the integration of Fe-Co-Al @ BTC Metal-Organic Framework (MOF) into a double slope solar still (DSSS) to enhance the evaporation rate. Three configurations were tested: MOF as a nanofluid in the basin water (Case I), MOF as a nanofluid with an atomizer (Case II), and MOF for thin film evaporation (Case III). A comprehensive 4E analysis—Energy, Exergy, Economic, and Environmental—evaluated the performance of the DSSS relative to conventional solar still (CSS). The MOF improved DSSS performance through its superior thermal properties and large surface area. Performance results showed notable improvements. Energy efficiency increased significantly, with Case III improving by 103 %, Case II by 82.3 %, and Case I by 53.3 %. Exergy efficiency witnessed more dramatic enhancements, with Case III rising by 162 %, Case II by 137 %, and Case I by 70.6 %. Accumulated distillate followed a similar pattern, with Case III rising by 92.12 %, Case II by 68.54 %, and Case I by 34.66 %. Case III demonstrated the most promising outcomes, achieving the lowest freshwater cost at 0.0122 $/L—a 26.22 % reduction from CSS. Additionally, the MOF integration resulted in CO₂ mitigation ranging from 1.49 to 2.2 tons annually, generating carbon credits between 37.13 and 54.94 $/year.

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
