Performance study on solar still using nano disbanded phase change material (NDPCM)

Abstract

The current work examines the enactment of a traditional single sloped type of solar still in the presence of crude wax as an organic phase changing material (PCM) and a low mass of nano-zinc oxide (ZnO) particles disbanded crude wax as NDPCM in terms of daily potable water output. To accomplish this goal, three identical solar stills were planned and constructed. Among these, one was an unchanged traditional still (Normal Still), another still was combined with crude wax based PCM (CW Still), and a third still was amalgamated with NDPCM (NDPCM Still). Earlier, the NDPCM was formed by combining 1.0 percent mass of zinc oxide nanoparticles with enough quantity of crude wax. The tests were carried-out in March 2021 at 11.0168° N, 76.9558° E. The results indicated that the addition of crude wax and specifically, the NDPCM increased the output of clean water by 50.24 percent and 65.17 percent, respectively.
