“…Quantitatively comparison The results of water productivity and water temperature of the present study were similar to experimental results. Rahbar et al [53] and Bafghi et al [54] Verification Quantitatively comparison The water productivity obtained from numerical solution has been compared with the experimental data for a given geometry reported by Islam and Fukuhara [71]. The results show that CFD simulation can predict mass productivity within the range of 15%.…”

a b s t r a c tComputational fluid dynamic (CFD) is a simulation tool which utilizes the applied and computational mathematics for fluid flow regimes modeling to predict the heat, mass and momentum transfer behavior. In recent years, the solution's accuracy of the CFD simulations became within the acceptable range demonstrating that CFD is a valid tool for performance analysis and design development for many thermal-hydraulic systems. This encourages researchers to use it in the modeling of evaporation and condensation phenomena or two-phase flow with a vapor-liquid phase change process and mass and heat transports through the interface simulation which is one of the urgent difficulties in the solar stills development and analysis. The aim of this is to introduce a comprehensive review work of the highlights that have been made through the recent years for most important studies about the CFD approach as a tool for performance prediction and analysis in addition to design improvement and development for solar stills. This study is supported with a compact synopsis in the form of, computational domain (two or three dimensional), CFD software utilized, operating and geometrical parameter range, simplified assumptions and the better CFD results.

“…Soliman (1976) suggested the concept of high temperature solar distillation (active solar distillation system). Worldwide, many researchers (Rai and Tiwari, 1983;Lawrence and Tiwari, 1990;Tayeb, 1992;Tiwari et al, 2003;Dubey and Tiwari, 2008;Hamadou and Abdellatif, 2014;Ling et al, 2014;Huang et al, 2015;Sebaii et al, 2015;Feilizadeh et al, 2015;Rahbar et al, 2015;Morad et al, 2015;Nimr and Dahdolan, 2015;Dehghan et al, 2015;Taghvaei et al, 2015;Edalatpour et al, 2016;Tiwari and Sahota, 2017) have theoretically and experimentally studied different active solar distillation systems.…”

“…The researchers developed a new correlation for estimating the convective heat transfer coefficient which showed good agreement with the published well-known models Rahbar and Esfahani (2012-2). The same researchers improved the solar still productivity at different operating conditions by using CFD simulation work (Rahbar and Esfahani 2013;Rahbar et al 2015). The authors and their colleagues carried out extensive experimental work to improve the performance of various types of solar still.…”

This paper is aimed to improve the productivity of an existing conventional single slope solar still with modifications. In this study, the conventional solar still is modified by using reflectors, jute cloth and improved glass angle. The modified still productivity and performance are investigated experimentally and compared to that of conventional solar still. The results demonstrated that solar still performance is improved with the 10o glass angle due to better water flow properties and higher solar radiation fall on the still. The results reveal that, with all combined modifications, the water productivity and efficiency of modified solar still increase by 72.18% and 41.51% respectively more than the conventional one. This implies that modified solar still could be adopted for higher water productivity at a lower additional cost.
