ABSTRACT = {This work aims to investigate numerically the influence of the buoyancy ratio and the Dufour parameter on thermosolutal convection in a square Salt Gradient Solar Pond (SGSP). The absorption of solar radiation by the saline
water, the heat losses and the wind effects via the SGSP free surface are considered. The mathematical model is
based on the Navier-Stokes equations used in synergy with the thermal energy equation. These equations are
solved using the finite volume method and the Gauss algorithm. Velocity-pressure coupling is implemented
through the SIMPLE algorithm. Simulations of the SGSP are performed for three values of buoyancy ratio (<i>N</i>
= 1, 2 and 10), three values of Dufour parameter (<i>Df</i> = 0, 0.2 and 0.8) and some sample meteorological data
(Tangier, Morocco). Results show that the highest dimensionless temperature of the storage zone is found for
<i>N</i> = 10. In the same zone and for the same value of <i>N</i>, the dimensionless salt concentration decreases very slightly
versus time (unlike for <i>N</i> = 1 or 2). Moreover, increasing Df from 0 to 0.8 causes a decrease in the dimensionless
temperature of the SGSP storage zone and this decrease is more pronounced for <i>N</i> = 1 and <i>N</i> = 2.},
