Conference paper


In this work, a mathematical model was developed to predict the amount of wáter to be evaporated depending up on the intensity of solar radiations, size and material of the concentrator and absorber. A parabolic concentrator Is used as a heating source. Solar energy is focused by the concentrator on an absorber which contains salt water. Water gets heated and converted to steam. The steam is then condensed by the condenser to get purified water. These results were utilised to develop a mathematical model which predicts the time of evaporation of the impure water. The model was validated with experimental results obtained for different months. The correlation coefficient was calculated and found to be 0.93.
