Abstract

The solar thermal applications existing to investigative relationships of absorbing materials of water flowing over glass cover through the influence of PCM and nanoparticles for the enhancement of a single-slope single-basin solar still are presented and discussed. The results are compared with and without PCM and nanoparticles summer days for a conventional solar still. Numerically designed and experimental annotations have been written for the investigative solutions for the temperature of flowing water, glass cover, absorbing materials (FWCW and FWJW) and PCM and nanoparticles basin liner, respectively. The 24 h distillate manufacture rate of the solar still has been enhanced to usage of drip button through pure saline water to absorptive influence of FWCW capability is 70.02% and during (24 hours) daily distillate harvest of FWCW is 9.429 kg/m<sup>2</sup> day, water flowing glass cover influence is 13.37%, respectively. A solar still analysis of Fourier coefficients with (6 to 6) harmonics Fourier series has been used for enhancement, and it is found to be a good representation of the observed variation. It is a good treaty among theoretical and experimental annotations of the structure.
