description The challenging efforts of this project have been designed to explore the abundance of renewable solar energy for the desalination of the inexhaustible seawater resource for the production of the most critical clean water resource necessary for the human consumption and existence, in particular to the poorer rural populations. The working principle of a solar still has been based on the heat transfer processes of three major components of the solar still (glass cover, seawater and basin) and its surrounding as a result of exposing the system to the solar irradiance. Two analytical approaches have been utilized to develop the theoretical model and the numerical model by forward finite difference approach for predicting the solar still performance. However, the numerical model has shown to be significantly far more accurate in predicting the experimental results than the theoretical model, particularly in a less consistent and varied solar irradiance during the latter part of the afternoon hours. At the same time, the optimization of the single slope solar still as a Simple, effective, safe and user friendly water treatment device, for the production of clean water has been experimentally verified.
