The Effect of Cotton Cloths on the Performance of the Solar still

Abstract:

In this study the conventional still is modified with cotton cloth at the inner wall surfaces to improve the performance of the still. The main purpose of this experimental study is to make use of the heat available on the inner wall surfaces of a basin by using cotton cloths. Two single-slope solar stills with the same area of 1mx0.5m are fabricated and tested. The hourly amount of extracted distilled water, the various temperatures and the insolation were observed for one month period (April 2014). The results were performed by comparing with conventional solar still and cotton cloth still. The experimental results clearly shows that, by reducing transfer of heat from inner surfaces to the outer surfaces with the help of cotton cloth the modified still gives yield about 13.3% higher than the conventional still.
