The SGSP is continuously exposed to constant solar radiation intensity, which is assumed as the maximum value of daily solar radiation. The difference in solar irradiance between cases was represented by the dimensionless parameters Ra and RaI. The solar radiation is absorbed by the bottom surface of SGSP, and thermosolutal convection is gradually forming in SGSP. The effectiveness of a porous layer in improving the thermal storage capacity of SGSP is discussed in this section. Firstly, thermal

The salt gradient solar pond (SGSP) can capture and store a large amount of solar energy for a long time, making it an efficient and economical solar energy facility. The long-term operational stability of SGSP can be damaged by interface erosion, which is caused by thermosolutal convection. Attaching porous layers is a promising approach to slow down interface erosion. In this study, we simulated the unsteady thermosolutal convection in SGSP with Lattice Boltzmann methods (LBM). The effects of a porous layer on salinity gradient stability are analyzed with boundary equilibrium and marginal cr...
