using solar energy systems is a practical solution for production of potable
water and particularly in remote areas, which suffer from lack of drinking water due to
poor infrastructure. It is possible for a small distillation system to be a practical and
economical solution for current and future demand for potable water with availability
water resources and large amounts of solar radiation. Therefore, productivity that
could be increased by increasing the model's ability to store the heat energy needed
to maintain evaporation was discussed using nanoparticles dispersed in paraffin wax
beneath the basin. In this paper, the main objectives of the study are to obtain the
optimum parameters of PCM mass, NPCM mass, water mass and solar radiation to give
the best productivity of the model inside the atmosphere of Najaf city, a numerical
study involving the study of the performance of single-slope solar still using different
masses of PCM with and without nanoparticles. Nanoparticles is used to improve
thermal conductivity of paraffin wax. The most commonly used paraffin wax (PCM) and
Al2O3 (nanoparticles) complements its specific thermal properties with fusion
temperature where the main active properties are studied. The numerical solution was
done using COMSOL 5.3 software and the results were compared with previous studies
and showed that a good agreement. Also, the results showed that the use of 1 kg of
PCM represent optimal amount of enhancement, and thus using of 3 Vol.%
concentration of Al2O3 nanoparticles dispersed in 1 kg of paraffin wax gives the
possibility of improving the traditional single slope solar still daily productivity by about
20%.
