Analysis of solar still with nanoparticle incorporated phase change material for solar desalination application

In the present scenario, heat storage system started to play its role in every field including solar thermal applications. This paper mainly deals with the application of heat storage medium in solar desalination still applications. This research concerns with the theoretical analysis of latent heat energy storage with the incorporation of nano particles. In this research, paraffin wax is selected as the phase change material with 0.3 weight% of nano particles such as TiO₂, CuO and Graphene Oxide. It is found that Graphene Oxide with paraffin gives the higher results comparing with the other nano particles. The thermal conductivity increased to 0.8 W/mK for Graphene Oxide nano composite and the predicted results shows that the productivity is quite high for paraffin wax with Graphene Oxide. Mathematical modeling was carried out and the results indicate that the solar still with phase change material incorporated with nano particles gives higher results than the conventional solar stills and Graphene oxide with paraffin is found to be the best nano particle for solar desalination still application. So it is best to incorporate Graphene oxide nano particle with paraffin for the experimental setup to achieve higher productivity than conventional one.
