Diffusion of single-effect vertical solar still fixed with inclined wick still: An experimental study

Abstract

In this research work, in place of multi effect unit I use single effect unit solar still for the same ambient condition. By using the convention mode, the movement of vapor from inclined wick to single effect unit is done easily. In place of multi effect diffusion solar still under actual weather conditions, the experimental investigation of a single-effect diffusion solar still which is combined with inclined wick solar still is conducted. In this research work, by the mode of convection to study whether transportation of vapor to multi-effect diffusion solar still from inclined wick solar still is occur sufficiently. On single-effect solar still the absorption of solar energy occurs that means the heating of vapor from inclined wick solar still by single effect mode of solar still. It was found from the experiments that in both seasons (Summer as well as Autumn) the multi effect diffusion solar still can be heated easily because this solar still directly or indirectly absorbs the solar radiation. With the simulated results the experimental results completely satisfied. The daily horizontal solar radiation doesn’t correlate with the daily yield. The daily solar radiation which is falling on the solar still is completely correlate with the daily yield. When the daily horizontal solar radiation were 13.6 MJ/m2 day and daily solar radiation which is falling on the solar still were 18.4 MJ/m2 day then from the experiments, it is found that the daily yield was 4.88 kg/m2 day.
