Theoretical and experimental investigations on solar distillation İYTE Gülbahçe Campus area seawater

Abstract

The world demand for potable water is increasing steadily with growing population. Water desalination using solar energy is suitable for potable water production from brackish and seawater.In this study, a solar distillation in a single basin is studied theoretically and experimentally in İzmir Institute of Technology Gülbahçe Campus area. The still was constructed using a 2100 mm x 700 mm base area, and the glass cover of still inclined at 38 0. Temperatures of glass cover, seawater inside the still, seawater interface, inside moist and ambient air and humidity was recorded continuously and distilled water was measured for each hour.Afterwards, to obtain extra solar energy, the aluminum reflector (2100 mm x 500 mm) was assembled to the still and effect of the reflector on the still productivity was examined.And also in this study, theoretical study was examined to describe the energy balances for the glass cover, seawater interface, black plate at the bottom and overall still and also to find still productivity.
