Abstract

Water and energy are two inseparable commodities that govern the lives of humanity and promote civilization. Unfortunately, humanity has a severe shortage of drinking water, although water represents 73% of the surface of the planet as seas and oceans. Several technologies for desalination of brackish or saline water are apparent around the worlds, such as reverse osmosis, electrodialysis...etc. These techniques are characterized by high energy consumption and adverse ecological effects on the climate. The use of renewable energy for water desalination gives a great hope, especially in arid and deserts area where solar energy is available. Relatively low needs for drinking water, solar distillation appears as one of the interesting methods. However, the productivity of a conventional solar still was not very satisfied. With a view to ameliorate the yield of the solar still, our study aims at the effect of coupling a spherical solar still with a flat plate collector on the yield of the fresh water, we have to compare between the productivity of a spherical solar still and conventional one. After having established the thermal balances of the various solar systems (plate still, spherical still, plate still-collector and spherical still-collector) at instationary regime, the differential equations are solved by using 4^th order Runge–Kutta method. The numerical results obtained allow to determinate the percentage of improvement caused by coupling a spherical solar still with a flat plate collector on the yield of the fresh water.
