Abstract

ABSTRACT: The present research paper deals with the theoretical and experimental investigation of solar stills with two different thermal energy storage materials, namely, marble pieces and sandstones. To carry out this research, three solar stills of 1 m square area have been made. All solar stills have been provided with a glass cover and a cooling and dripping arrangement for reducing top heat loss and maintaining a constant level of water. It has been found that the use of sandstones as storage materials and the cooling and dripping arrangement have a remarkable effect on the distillate output of a solar still. The set-up has been used to augment the distillate output throughout the day. Theoretical results have also been compared with the experimental results and have been found to be in good agreement.
