Abstract

This study developed low-cost nano-graphite-textural wick for the interfacial evaporation process. The nano-graphite was mixed with black dye and saturated a white cotton wick. A simple glass cup was used as condenser. The glass cup has simple geometry that can be easily utilized for any number in array form according to required demand. Moreover, readymade (waste) or specially manufactured glass cups from recycled glass materials can be used with very competitive low-cost water production systems. The saline water inside the wicked cup is absorbed in the wick texture and spreads in a larger exposed interfacial surface area. Results showed superior performance of the developed system with productivity and efficiency enhancement of 30.9 % and 31.4 %, respectively, reaching 5.235 L/m²day freshwater yield and 42.7 % daily efficiency. Moreover, the developed system was able to produce freshwater with a very competitive cost of 9.9 $/m³ compared with other techniques in literature ranging from 15 to 25 $/m³ in most cases. This cost can be further enhanced for developed large-scale projects. Large projects enable mass production of recycled materials and other device components with lower operation and maintenance costs with higher thermal efficiency due to using arrays of cups with less heat losses expectation.

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.
