The aim of the study is to enhance the productivity of solar stills using an unsaturated porous medium (sand) initially saturated by salty water and using concentrating reflector. This paper concentrates on the mathematical model for the porous medium and its solution using a finite volume approach. Previous studies for solar still, using porous medium have been mainly concerned with ... Read more

This current work studies the effects of initially saturated porous medium and humid air region on the water vapor condensation. The experiments of the present study were conducted on a double slope solar still (DSSS). The DSSS liner dimension is 1.9 m by 0.86 m by (0.02 m, 0.03 m and 0.04 m). The effect of porous medium thickness on ... Read more

The goal of the study is to enhance the productivity of solar stills using an unsaturated porous medium initially saturated by salty water and using concentrating reflector. This paper concentrates only on the mathematical model for the porous medium and its solution using a finite-volume approach. The previous studies dealt with wick medium with high water content and liquid saturation ... Read more
