Also, there is a problem with the pollution of water resources due to sewers leakage, pesticide runoffs, etc. Conventional stills have limitations due to low productivity. Hence research and development are being conducted to enhance the productivity of stills. The works of literature reported that numerical and flow analysis of heat transfer in tubular still and concluded that productivity is sensitive to the glass surface, basin water temperature and also the sharp corners in the sloped solar stills. So, a new modified curved surface under the basin has been implemented which helps in supporting the basin and also in condensing the evaporated water inside the still. The present research addresses the heat and fluid flow inside a still due to geometrical modifications are done on the basin and compares the performance of each design by varying the location of it (D/2 and D/3) as shown. The solar still performs best when the curved water basin is at 1/2nd of the still diameter at higher Rayleigh numbers. When compared to conventional stills, the tubular still with a linear basin at D/2 dissipates 31.4% more heat. This means a better production rate of solar stills at higher Rayleigh numbers.
