摘要

Solar desalination performance enhancement through the use of copper and silicon carbide nanoparticles in solar still systems is discussed in this research. The objective of the work is to improve thermal conductivity, heat absorption, and general efficiency of the solar desalination processes. For the sake of comparison, two similar solar stills were prepared in order to investigate influence of these nanoparticles under standard conditions. The experimental setup incorporated specified amounts of Cu and SiC nanoparticles into the working fluid of the solar stills, productivity, and efficiency being evaluated under different operational conditions. The outcome shows enhanced day-to-day desalination capability through the addition of nanoparticles. High thermal conductivity of copper nanoparticles enhanced the efficiency of the solar still by 9.62% at an optimized volume concentration of 0.6%. Likewise, stability and better thermal characteristics of silicon carbide (SiC) nanoparticles increased the productivity 88.97% by integration with phase change materials (PCMs). The incorporation of SiC nanoparticles also enhanced the heat transfer coefficients for phase-change processes giving a uniform temperature profile within the system and faster rates of evaporation. The work also looked at the interaction between nanoparticles and PCMs integrated into different systems. The SiC-enhanced PCMs enhanced the overall productivity by 60.37% and thermal efficiency by 68.29% compared to typical structures. The incorporation of copper rods containing nanoparticle–incorporated PCMs again improved latent heat storage ability even further and attained up to 4.27 L m-2 day-1 of daily production under specific conditions. The results of statistical analyses revealed that both Cu and SiC nanoparticles increase the performance of low-temperature solar desalination, with SiC as more stable and thermally conductive than Cu at identical concentrations. As exemplified by these results, there is enormous room to advance ST (Solar Thermal) dynamics in SWD (solar water desalination) in terms of energy efficiency and freshwater production at a reasonable cost through nanoparticle enhancement.
