Abstract
In this paper, an experimental attempt has been made to study the performance of the desalination system comprising of corrugated and wick absorbers of solar stills. Therefore, two solar stills are designed, fabricated and assembled to study and compare their performances. The first one is a conventional solar still (CSS) and the second is a corrugated solar still (CrSS). The performance of the CrSS with and without wick and reflectors is tested and compared with CSS at the same conditions. The influences of saline water depth (1, 2, and 3 cm) on the performance of the CrSS and its modifications have been investigated. Results showed that integrating wick and reflectors with corrugated still enhance the productivity. During experimentations, the productivities of CrSS with wick and reflectors are about 145.5% higher than that of the conventional still, at saline water depth of 1cm. In that case the daily efficiency and estimated cost of 1 l of CrSS (with wick and reflectors) and CSS are approximately 59%–0.025 $, and 33%–0.048 $, respectively.
