Abstract
In this communication, an analysis of an inverted absorber solar still, with water flowing over the condensing surface, has been presented. Analytical expressions for the hourly variation of various temperatures namely, water, condensing cover, and flowing water, the yield and the instantaneous thermal efficiency have been derived in terms of design and climatic parameters. Numerical computation has been carried out for a particular day of Delhi weather for an inverted absorber solar still with water flowing over the condensing cover. The results have been compared with those of an inverted absorber solar still without the water flow over the condensing cover. It is found that for an optimum 10cm depth of water in the basin the yield is increased by about 11 % when there is flow of water at the rate of 0.5kg/s.
