Even though most part of the planet is covered by water,
many regions experiences situation of severe draught. Solar still
devices presents as a solution to scarcity of water in hot climate
regions, where electricity does not reach. These devices are
very simple and present ability of converting available saline or
low quality water into potable water. In this work, multiphysics
of an inclined square solar still device are numerically
studied through finite volume method. The phenomenon of
double-diffusion natural convection is considered for problem
modeling. Velocities, temperature and concentration fields are
obtained when Rayleigh number is varied from 104 to 107.
Solar still capacity is analyzed through condensation rate
parameter, for the mentioned Rayleigh number range.
