ABSTRACT={Solar Ponds are large areas consisting essentially of three density-stratified zones: an energy storage zone (Layer Convective Zone ’LCZ’), a thermal insulation zone (Non-Convective Zone ’NCZ’), and a protection zone against natural hazards such as wind and dust (Upper Convective Zone ’UCZ’). The performance and efficiency of solar ponds depend on the stability of the gradient layer. The latter is subject to double molecular diffusion of heat and mass and hydrodynamic movements (double convective diffusion) tend to be homogenized. The coexistence of different diffusions in the stratified system constitutes complex instability phenomena whose physics is poorly known until today. In this study, preliminary experiments showed that the stability of a solar pond could be increased by using phase change materials (PCM) placed at the bottom of the pond.}}
