چکیده
The analysis of entropy generation provides valuable information for the design and optimization thermal systems. Solar stills are used water desalination purification. Using renewable energies, they provide a sustainable solution drinking supply in remote areas off-grid situations. This work focuses on 3D numerical study two-stage solar still subjected to natural double diffusion convection phenomenon presence CNT nanoparticles. effects Rayleigh number, buoyancy ratio, nanofluid concentration thermal, solutal, viscous irreversibilities flow structure were studied. results show that increasing ratio leads an increase solutal generation. this also total is minimal positive volume force ratios, N, at nanoparticle fraction around 3%, negative N 4%.

The problem of double-diffusive natural convection of Al2O3 -water nanofluid in a porous triangular enclosure in presence of heat generation has been studied numerically in this paper. The bottom wall of the cavity is heated isothermally, the left inclined wall is non-isothermal and the right inclined wall is considered to be cold. The concentration is higher at bottom wall, lower at right incl...
