Performance Enhancement of a Solar Still by Using Water-Based Hybrid Nanofluid

Abstract

In this article, a theoretical comparative study of modified solar still (MSS) and conventional solar still (CSS) was performed based on the same geometrical, metrological and operating conditions. The MSS consist of a hybrid nanofluid made with 1% volume concentration of hybrid nanoparticles of alumina and copper (Al2O3(0.5%) + Cu(0.5%)) with base fluid (water). The hourly evaporative heat transfer coefficient, yield, accumulated productivity, temperature of the glass, basin, and base fluid with/without hybrid nanoparticles were estimated. Results revealed that the temperature of all components of MSS and CSS achieve their maximum values at 3.00 PM. Moreover, the accumulated productivity for MSS (with hybridnanofluid) increase by 11.6% as compared to CSS(without nanoparticles). © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
