Abstract
Dwindling potable water is a big concern for the whole world in general and developing nations in particular. Solar still is found to be suitable for the production of potable water at low cost, especially in the arid regions. In view to improve the distillate output of the solar still, the augmentation of the sensible and latent heat, a storage material was needed. For the purpose, wax filled metallic finned cups were used. In this paper, an attempt was made to investigate (experimentally and theoretically) the performance of a conventional solar still integrated with wax filled metallic finned-cups (MSS). Outdoor experiments were conducted on conventional solar still (CSS) and CSS augmented with wax filled metallic finned-cups, in the month of January and February 2019, at Raghogarh, Guna ( 24º39'N, 77º19'E, India). Linear regression model proposed by Kumar and Tiwari was used to evaluate the performance of solar stills. An improvement of 15.63 and 16.95% in evaporative and convective heat transfer coefficients (from water to condensing cover) have been observed in MSS, as compared with the CSS respectively. It was found that the overall efficiency of MSS increased by 24.64% in compared with the CSS.
