AI Article Synopsis
- Scientists are researching ways to increase water yield from hemispherical solar stills (HSS) by using reflective materials.
- In an experiment, one solar still used standard design (HSS) while the other had aluminum foil reflective walls (HSS-RAFW).
- The HSS-RAFW produced 4.1 kg/m of distilled water, which is a 22.21% increase over the HSS's 3.36 kg/m, and it also showed better energy and exergy efficiencies.
Article Abstract
Various scientists are looking for effective and easy solutions for the augmentation of yield from the hemispherical solar still (HSS). In this study, aluminum foil sheet was used to reflect the intensity, hence augmenting the evaporation rate and daily yield. Experimentations were conducted on two SS: the first SS is HSS; the second SS is HSS with reflective aluminum foil sheet walls (HSS-RAFW). The highest distilled water production from the HSS and HSS-RAFW is 3.36 and 4.1 kg/m, respectively. Compared to the HSS, the yield of distilled water was augmented by 22.21% when using the HSS-RAFW. The daily energy and exergy efficiencies (EnE and ExE) of the HSS are 26.27 and 1.04%, respectively, and the daily EnE and ExE of the HSS-RAFW are 32.75 and 1.71%, respectively.
