Since there is a lack of turbulent double diffusive. We validated the double-diffusive convection and turbulent convection in our model separately. First, we validated double diffusion model by simulating the laminar double-diffusive convection. Secondly, we validated the turbulent natural convection in a cavity. The double diffusive natural convection in a cavity was simulated and compared with a previous study [32]. The domain and boundary conditions are identical to that in Ref. [46] and

The salt gradient solar pond (SGSP) is a low-cost and large-scale solar energy capture and storage device. The stability of the non-convective zone (NCZ) is critical for the well-functioning and efficiency of SGSP. To understand when and how SGSP lost its effectiveness, the turbulent double-diffusive convection in solar ponds was first solved numerically with a Large Eddy Simulations (LES) model. The simulations show that attaching a porous layer or increasing the initial salt concentration effectively delays the destruction of NCZ. By increasing the initial salt concentration from 5.2% to 20....
