  • Experimental evaluation of double slope solar still augmented with ferrite ring magnets and a black cotton cloth
    Manoj Dubey, Dhananjay R. Mishra
    International Journal of Ambient Energy, 2022
    In this present work, an attempt has been made to do the comparative experimental and theoretical evaluation of two identical double slope solar still (2m×1mbasin area) of 15° top cover inclination kept in an east–west direction. Modified double slope single basin solar still is augmented with the permanent ferrite magnet (for reducing the surface tension of the water), triangular prismatic metallic structure (for reducing characteristic length) and black cotton cloth (for enhancing the surface area). Experiments are carried out at the geographical condition of JUET, Guna (Latitude: 24°39’N, Longitude: 77°19’E, India). Theoretical evaluation of the experimental result is carried out with the help of Kumar and Tiwari model based on the regression analysis. An increase of 60.24% is observed in the daily distillate output of modified still. The evaporative heat transfer coefficient and the total heat transfer coefficient have improved by 54.15 and 42.93%, respectively.
  • Experimental analysis of double slope solar still augmented with dye, pebbles and metal chips

    Double slope solar stills are reported to give lower yields in winter season. In this work an attempt has been made to improve the performance of still with double slope in winter. A comparative experimental and theoretical analysis of conventional and modified single basin still with double slope augmented with black dye, pebbles and iron chips (5 kg each) is reported in this manuscript. The experiments are carried out in the month of November and December in 2017 at meteorological conditions of Jaypee University of Engineering and Technology, Guna (Latitude: 24°39'N, Longitude: 77°19'E). Distillate yield in a modified solar still due to the augmentation has improved by 28.4% as compared with conventional solar still at a common water depth of 0.025 m, whereas its overall heat transfer coefficient and overall thermal efficiency are improved by 55.7 and 25.01%, respectively.

  • Experimental and theroretical evaluation of double slope single basin solar stills: Study of heat and mass transfer

    Fme Transactions, 2019
    Experimental and theoretical analysis of the three single basin double slope solar stills with 15 ̊, 30 ̊ and 45 ̊ glass cover inclinations, are carried out at meteorological conditions of Raghogarh, Guna (Latitude: 24°39'N, Longitude: 77°19'E, India). The experiments are performed from 14th to 16th June 2017. Detailed energy and exergy analysis are carried out using theoretical model proposed by Kumar & Tiwari, based on regression analysis. It has been observed that the theoretical results obtained from evaluation have good agreement with the experimental results. Maximum fresh water is obtained from 15 ̊ inclined glass cover solar still (viz.4.66 litre of 14 h observation ) and contribution of 52% and 48% from east and west side of solar still respectively. At 15:00 h all the stills show maximum thermal efficiency viz. 23.69, 29.24 and 25.09% for 15 ̊, 30 ̊ and 45 ̊ cover inclinations respectively. It has been observed that maximum exergy is lost in basin followed by glass and water in all the double slope solar stills.
