“…Recently, many studies on the effect of flat plate external reflectors on basin-type stills have been reported [24][25][26][27][28][29][30][31][32][33][34][35][36][37], although few reports had been presented before the year 2000 [38][39][40]. The results showed that an external reflector can increase the solar radiation absorbed on the basin liner as well as the distillate productivity of the still if the reflector angle is set properly.…”

The effect of a flat plate bottom reflector on a vertical multiple-effect diffusion solar still coupled with a basin-type still is analyzed theoretically at 30 ∘ N latitude. The still has a right-angled triangular cross-section consisting of a horizontal basin liner, a sloping double glass cover, and the vertical multiple-effect diffusion still (multiple-effect section) at the vertical rear wall. A geometrical model was constructed to calculate the amount of solar radiation reflected by the reflector and absorbed on both the basin liner and the first partition of the multiple-effect section. The reflected radiation from the reflector can be a thermal input to the multipleeffect section both in cases where the reflected radiation is absorbed on the basin liner and on the first partition. It is predicted that the overall daily productivity of the still can be increased about 16%, 13%, and 29% on the spring and autumn equinoxes, the winter solstice, and the summer solstice, respectively, by adding the external reflector and setting the reflector inclination to the proper angle according to seasons.

“…Although there have been a number of studies on basin solar stills, there still remains room for discussion. For example, Ayav and Atagunduz [13] performed an experimental and theoretical investigation on a single basin but they did not use the correlations related to external reflector in the numerical simulation. In addition, Tanaka [27][28][29] frequently analyzed the effect of adding reflectors to the basin solar still but did not use energy balance and external reflector equations simultaneously.…”

Abstract:In this study, a thermal model for estimating the efficiency of a basin solar still with an external reflector was introduced using the energy balance equations of different parts of the solar still. Then, in order to verify the precision and accuracy of this model, a basin solar still with an external reflector was constructed and some experiments were performed. The hourly temperature values for different places of the still and amount of distilled water were calculated using the thermal model and compared with experimental measurements. Comparisons show that the thermal model of the still is in good agreement with the experimental results. Therefore, it can be concluded that the introduced thermal model can be used reliably to estimate the amount of distilled water and efficiency of the basin solar still with an external reflector. Results also revealed that the efficiency of the solar still is low in the early hours, while it was enhanced 44% in the afternoon. Furthermore, it was concluded that the accumulated distilled water is 4600 mL/day and 4300 mL/day for theoretical and experimental examinations, respectively.

The basin solar still was developed by adding a magnetic treatment unit, it's energy 0.12 Tesla and two layer of glass provided with water between them. The study was conducted by testing the device by using magnetic water + double glass provided with water, non magnetic water + double glass cover, magnetic water + single glass cover, non magnetic water + single glass cover and control treatment (without additions). Intensity of incidence solar radiation in Basrah province during the month of April, Temperature in the basin solar still, glass cover surface, ambient, pH, water electric conductivity, productivity, density, physical and chemical properties were measured. Theoretical productivity and efficiency were calculated. The results showed that the average of solar radiation intensity is 889.55 W/m 2 . Temperature of basin solar still, glass cover surface and ambient was increased with increasing solar radiation intensity. The maximum of temperature in the basin water of solar still is 56.61°C at using magnetic water + single glass cover which has best performance compare with other treatments and having pH 7.03, minimum electric conductivity is 0.000672 S/m and density reached to 1000 kg/m 3 and gave highest efficiency at 32.55% and it's productivity improved by 50% compared with conventional.
