Day and night yield performance analysis of solar still for saline water using energetic materials with thermocol insulation

Abstract

A new approach is proposed to improve the performance of solar still. The Solar desalination process proves that the pure good water is produced without salt content from the salty water including the earth bore water and sea water. In this technology, the solar still along with solar energy absorber material such as Nano material (Aluminium Oxide) is used and getting high performance of solar still. Result shows a considerable increase in rate of pure good water production. When comparing with the various solar energy absorbing materials such as glass ball, pebbles, gravels, and Nano material, the Nano material gives more yield than other heat absorbing materials. The optimum water depth in the basin is measured as 30 mm. The slope of glass cover inclination is 450. The maximum day yield from saline water is 2.920 L/m2/day with thermocol insulation. The maximum efficiency of solar still when using Nano material is 4.9%.
