Abstract

This work presents a theoretical and experimental study of a double slope still with and without immersed fins compared to the single solar still monthly production. The influences of the distance between fins, fin heights, fin numbers and water layer thickness on the solar still production have been widely researched. From the obtained results, the distance between fins has no significant effect on the still productivity. Moreover, for fin heights from 2 to 5 cm, cause the productivity raising, when the fin heights are from 6 to 8 cm found an increasing in the still production. A larger fin numbers lead to a rising in the produced water amount. The water quantity augmentation in the basin makes the water productivity decreasing. The experimentally obtained results during the day June 11, 2016, show that the solar still with immersed fins productivity was about 15 to 27 % higher than that of the simple solar still, under the following conditions, i.e. mw = 42.61 kg, h1 = 3.6 cm, Vw = 3.5 m/s, lw = 5 cm and Nfins = 12.
