AN INVESTIGATION OF THE PARAMETERS INVOLVED IN SIMPLE SOLAR-STILL WITH INCLINED YUTE

Desalination of water has been one of the most important technological work undertaken in many countries, in particular Middle East. For thi s purpose, solar energy is the attractive familiar way in producing su ch fresh water where the cost of other energy is continuously increase d. This paper represents the experimental results carried out with a s olar still with inclined evaporating yute to study the effects of air gap, base slope angle and glass cover slope angle on the performance o f the still. In order to investigate the parameters involved in the st ill, three models have been designed, manufactured and tested against some experimental measurements on a still having 1m x 1m basin area. T he models have been designed in a way that it can give different base slope angle and glass slope angle. A comparison between the three mode ls has been made for three glass slope angles. The test results show t hat the model with base slope of 15 degrees and glass slept of 35 degr ees gives the best results, It gives a daily desalinated water quantit y of 5.6 liter/m(2).day.
