This study presents the results of a numerical analysis of a solar still's (SS) thermal performance and water production. It is proposed that low-income isolated populations in need of potable water utilize an SS for desalination. The SS under six distinct salt concentrations (0, 6, 12, 18, 24, and 30 g/kg) are the subject of the study. Adding phase change material (PCM) beneath the water sink was done to offset the decline in productivity caused by an increase in salinity, as previous experimental outcomes published in the literature have shown. By comparing those with published experimental data, the mathematical model and numerical approaches were found to be valid. The relative difference in temperature was under 2% while the relative difference in water production was under 3.5%. Unlike competing mathematical models, this one takes into account both the temperature and salt concentration when calculating water parameters. From 0 to 30 g/kg of salinity, the findings show that daily production drops. For every instance, the water temperature, the temperature difference between the water and the glass, the cumulative and hourly productivity were shown. The analysis also includes the heat flow behavior between PCM and water.

The most benefits of solar desalination are that it is cheap and environmentally good. This study investigated the potential of a novel biomaterial called Porites coral to enhance the efficiency of solar stills by storing energy in a porous medium. The final product was dubbed Coral Solar Still System (CSSS). When light levels are low, the Porites coral biomaterial releases the heat it has stored into the sea. The porous surface of the Porites coral also makes it a great absorber, which causes the water to get hotter since a lot of solar energy gets absorbed. The research was conducted based on the weather conditions observed in Thoothukudi, India. Results demonstrate a 12.6% improvement in productivity as compared to the conventional solar still (CSS) when energy storage was accomplished utilising a porous media containing Porites coral. When compared to the CSS, the CSSS achieved a 13% increase in energy efficiency and an 11% improvement in exergy efficiency.
