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.

An experimental study was conducted at Rewa, India (24°32′′N, 81°18′′E) in order to investigate the effect of the material of the body of a basin type solar still on its performance. Two single sloped basin type solar stills of G.I. sheet and F.R.P. respectively were constructed of equal basin area and size and were tested by keeping them side by side under identical conditions. Due to considerably lower thermal conductivity of F.R.P. as compared to that of G.I., around 30% higher productivity was observed in the former. The base heat loss as calculated with the help of the thermal model, in case of F.R.P. still was observed to be 36% which was much lower than 53% for G.I. still. The efficiency of the F.R.P. still was obtained as 32% whereas for G.I. still it was 26%.

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.

An experimental small scale desalination system where solar energy as the main heat source was conducted in a remote area of Cox’s Bazar district of Bangladesh. In this investigation, the performance of three solar stills with transparent glass cover was studied. Treated sea water was given to the solar still and the quantity of distilled water from three solar stills was measured per day and the effectiveness of the stills was compared. The performance of these stills was checked for 20 days. The different parameters i.e. ambient temperature, Salinity, pH, Unionized NH3, Iron, NO2-N, Chlorine, DO and amount of distilled water were studied and analyzed. The average amount of water produced by the still (1) was 455 ml, still (2) was 394.75ml and still (3) was 339.25 ml. The total amount of water produced by the still (1) was 9100 ml, still (2) was 7895 ml and still (3) was 6785 ml. The average desalinated water were obtained 1.06 liter/m2/day, 0.98 liter/ m2/day and 0.95 liter/ m2/day from still 1, 2 and 3 respectively. DOI: http://dx.doi.org/10.3329/jbau.v11i1.18229 J.

Performance a double slope of the solar still Integrated With or without parabolic trough collector is investigated experimentally. To improve the output of a double slope solar still, a number of initiatives have been undertaken, using wax as a phase change material (PCM) with a parabolic trough collector. A parabolic trough collector (PTC) transfers incident solar energy to the solar still through a water tube connected to a heat exchanger embedded in used microcrystalline wax. Experiments were carried out after orienting the basin to the south and holding the water depth in the basin at 20 mm. According to the results obtained, the solar stills with parabolic trough collector have higher temperatures and productivity than solar stills without parabolic trough collector, as well as the ability to store latent heat energy in solar still, allowing fresh water to condense even after sunset. In addition, the parabolic trough collector with phase change material in the double slope solar improves productivity by 37.3 % and 42 %, respectively.

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.
