Abstract Today, availability of clean water is hard as the residents are expanding and moving fast to achieve rapid urbanization as a result need for clean water has been raised. Solar stills are the solution to desalinate to obtain pure water. This paper represents the theoretical and experimental study of tubular solar still with and without fins. The reading was recorded from 8:00 AM to 6:00 PM. Efficiency of TSS with fins and without fins are 23.39% and 13.76% respectively. The rate of irreversibility from the basin of TSS with flat is higher than TSS with finned absorber. Similarly, the rate of irreversibility from water is significantly reduced using finned absorber. Also, the exergy efficiency of TSS with finned absorber is higher compared to TSS with flat absorber.

In the present study, a new experimental approach is proposed to enhance the performances of the conventional single slope solar still using vertical basin at inner wall surfaces. Main objectives of this study are, to increase the distilled output of solar still by utilizing heat energy available inside vertical surfaces and to find out the optimum thickness of vertical basin experimentally. The experimental system involves six identical solar stills, one of the stills is conventional and remaining stills have vertical basin with different thicknesses (3, 6,9,12 and 15 mm). Solar stills are fabricated with an effective area of 0.009 m2 and the transparent glass angle is 11°. The experiments were conducted on 19.02.2016 with depth of water 20 mm. The results show that (i) productivity of vertical basin solar stills are higher than the conventional still, (ii) heat loss from inner wall surfaces to outer wall surfaces are reduced considerably in vertical basin still  (iii) optimum thickness of vertical basin is 12 mm. To conclude introducing vertical basin in conventional still improves the performance of the still.

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.
