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 Sol-Gel method. The Aluminium Oxide particles were characterized by XRD, SEM, EDS, and FTIR etc. In this experiment TN+30 was used as phase change materials and Aluminium Oxide Nanoparticles used for energy storage materials. The water is taken about 15(ltrs) and the optimal depth of water found to be 1cm. The energy materials TN+30 along with Al2O3 shown improvement in collection efficiency with 200ppm and 400ppm was 21.65% and 32.97% when compared with PCM.
