Abstract: Now-a-days, encountering with lack of potable water is one of the major problems in developing as well as under-developed countries. There is a lot of saline water in earth hence to solve problem of potable water, the saline water needs to be converted into potable water. A device, which converts saline water into drinkable water, is called solar still. Solar still is a device which uses process of solar distillation. Solar distillation method is an easy, small scale and cost-effective technique for providing drinking water. It requires an energy input as heat and the solar radiation can be the source of energy. In every efficient solar still design, water temperature, distillate output, and difference between water temperature and inner glass cover temperatures are very important. Many scientists of world have worked on solar still to increase the output. There are different types of solar still designs available with different mechanical structures and performance characteristics including single slope solar still, hemispherical solar still, pyramid solar still, double slope solar still and so on. In this thesis, the main aspect of research is focusing on single slope solar still with single basin along with its design, requirements of components, implementation and analysis of the effect of slope of glass on performance of this design in providing drinking water from saline water. In this work, an attempt is made to develop the experimental setup to perform experiments on solar still having movable slope. Proper insulation and sealing is ensured to trap the heat in the basin without any leakage of water and heat. In-depth study of literature is done on the basis of different types of solar still, simulation done as well as designing done on them. Based on the literature, it has been decided to develop the experimental setup of single basin solar still with adjustable/ changeable slope with some modification for experimentation considering different slope angles to check effect on temperature and efficiency of solar still. An attempt will be made for experimental evaluation and cfd analysis at different slope angles to find the angle of slope at which the efficiency is more. DP-1 status involved thorough design, 3D model and parameters/ elements needed for experimentation. In MSR, the actual working model along with analysis/ reading based on experimental evaluation is carried out and in DP-2 CFD-analysis and comparison between experimental and CFD-analysis is done.
