Abstract
This works reports performance of corrugated wick in a “V” type solar still. The still was tested in two configurations: plane wick integrated with drip system and corrugated wick integrated with drip system. A mathematical modeling has been proposed to validate experimental results. The experiment was performed in Tamilnadu, India climatic conditions (11° North 77° East). Experimental investigations on productivity and internal heat transfer are analyzed. The results indicate that the mean standard deviations between theoretical and experimental values are less than 7% (temperature of rippled wick), 3% (temperature of glass in rippled system), 6% (temperature of flat wick) and 3% (temperature of glass in flat system) an average for the working hours of the day. The distillate yield produced was 2800 ml/m2/day by plane wick and 2200 ml/m2/day by corrugated wick.
