A floating sponge solar still design and performance
TLDR
In this article, a floating sponge solar still designed for sea water desalination is presented, where an optimum thickness of 150mm was obtained for the tested material which had a density of 16 kg/m.Abstract:
A floating sponge solar still designed for sea water desalination is presented. Experimental evaluation of the still performance with possible practical applications are also given. These experiments were carried out on a laboratory model which was built and tested under outdoor climatical conditions. A single-sloped cover was used with four different sponge thicknesses to investigate the still performance. An optimum thickness was thus obtained for the maximum productivity. This optimum thickness was found to be 150mm for the tested material which had a density of 16 kg/m. The maximum productivity of the still was found to be 3.1 litres/day, obtained with the optimum thickness of sponge material and the single-sloped cover. A double-sloped cover was also used with the optimum sponge thickness obtained from the previous tests to examine its effect. The results obtained show that the double sloped cover increased the productivity of the still by some 58%, to 4.9 litres/day, with the same still efficiency. ...read more

Improving the performance of solar still using vibratory harmonic effect
TL;DR: In this paper, a vibrator is used to generate forced vibration to excite the flexible packed media to break the boundary layer and surface tension of the saline water and improve convective heat transfer, and also to assist condensed polycarbonate glass cover to assist the condensed droplets to slide down before it becomes bigger and possibly falls down in the basin.

Influence of Porosity on the Productivity of Floating Sponge Solar Stills
TL;DR: In this article, the authors investigate the effect of porosity on the productivity of a floating sponge-type solar, still which is designed especially for seawater desalination, and show that the productivity increases with the increase of the sponge porosity.

Periodic theory of solar still
TL;DR: In this paper, the authors present a periodic analysis for estimating the distillate output of a single-basin-type still with large water depth, when the still (i) rests on the ground and (ii) is mounted on a stand.
