Enhancing Solar Still Productivity with Aluminium Oxide Nanoparticles and Phase Change Materials

The present study is focused on the integration of phase change materials (PCMs) and Al₂O₃ nanoparticles into solar stills presents a promising approach to enhance their efficiency. This paper explores the design and performance analysis of a solar still system incorporating PCMs and Al₂O₃ nanoparticles with different concentration like 200ppm and 400ppm. The primary goal is to investigate the impact of these enhancements on the solar still’s productivity and thermal efficiency.The Aluminium Oxide Nanoparticle were synthesized by chemical co-precipitation method. XRD and TEM were used to characterize the aluminum oxide particles. In this study, Aluminum oxide nanoparticles were employed as thermal conductivity materials, while TN+30 were utilized as a phase change material. After taking about 25 (liters) of water, it was discovered that 1 cm was the ideal depth. Compared to PCM, the energy materials TN+30 and Al₂O₃ increased collection efficiency with 200 ppm and 400 ppm of 21.65% and 32.97%, respectively.
