![عکس صفحه اول مقاله: Experimental and numerical analysis of sodium-carbonate salt gradient solar-pond performance under simulated solar-radiation Experimental and numerical analysis of sodium-carbonate salt gradient solar-pond performance under simulated solar-radiation](/preview/png/245480.png)
The objective of this study is to investigate experimentally and theoretically whether sodium carbonate (Na2CO3) salt is suitable for establishing a salinity gradient in a salt-gradient solar-pond (SGSP). For this purpose, a small-scale prismatic solar-pond was constructed. Experiments were conducted in the laboratory under the incident radiation from two halogen-lamps acting as a solar simulator. Furthermore, a one-dimensional transient mathematical model that describes the heat and mass transfer behaviour of the SGSP was developed. The differential equations obtained were solved numerically using a finite-difference method. It was found from the experiments that the density gradient, achieved using sodium carbonate salt, can suppress convection from the bottom to the surface of the pond.
