Abstract

The present investigation centres on the empirical examination of a solar photovoltaic (PV) system that is integrated with a dome-shaped solar still (DSSS) in order to facilitate the process of desalination. The objective is to increase the production of freshwater through the utilisation of saline water at elevated temperatures. The assessment of the DSSS system's efficacy is conducted through the examination of various parameters, including water yield, energy, exergy, concentrator performance, and economic feasibility. The study's results demonstrate that the DSSS system's water yield, energy, and exergy were evaluated under varying inlet temperatures and mass flow rates. The study recorded the water yield, energy, and exergy at 4.73, 4.27, and 4.91 l/m?, respectively, with respect to the ambient inlet temperature. The water yield was observed to range from 6.9 to 7.7 litres per square metre under different input temperatures and air mass flow rates. The DSSS system's energy and exergy efficiency were evaluated, indicating encouraging results for various inlet air temperatures. Furthermore, the economic evaluation revealed that the rate of freshwater production was cost-effective in comparison to conventional solar stills. In summary, this research offers empirical proof of the efficacy of a solar photovoltaic-powered dome-shaped solar still for the purpose of desalination. It emphasises enhancements in the output of fresh water, energy and exergy efficiency, and the economic viability of this technology.

期刊介绍： The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
