Abstract

The Compact Salinity Gradient Solar Ponds (CSGSPs) provide a viable alternative for thermal energy storage in numerous applications, especially in hot and humid conditions. This investigation examines the optimisation of CSGSPs by incorporating improved heat-storage materials. Microcrystalline paraffin wax, serving as the primary heat storage medium, is augmented with three distinct nanoparticles: Carbon Nanotubes (CNTs), magnesium oxide (MgO), and ferric oxide (Fe2O3) to enhance heat-transfer capacity. In this work, six distinct CSGSPs are explored to identify the impact of various heat storage media and enhance their capacity. Each experiment was done over 24 h, beginning at 00:00 and lasting for seven days. Experimental observations suggest that a high temperature of 51 °C may be attained over seven days while utilising microcrystalline paraffin wax combined with all three nanoparticles. Optimisation research was used to identify the parameters influencing the operating behaviour of the solar pond. The answer delivers a desirability of 97.6%. The findings demonstrate that the temperature may rise while providing a fair augmentation to the thermal energy storage medium. The temperature increased to 43.6 °C, and the energy increased to 18.66 MJ when all three nanoparticles were combined with microcrystalline paraffin wax in the CSGSP.
