Abstract: 

A Salt Gradient Solar Pond (SGSP) is a large reservoir of saline water, with the difference that a specific salinity profile is artificially created and maintained. SGSP receives thermal energy by incident solar radiation. The area of SGSP depends upon the design capacity of thermal/electrical power generation. The depth of SGSP is generally ranging from 2 to 5m and area 2 to 12 km2 . In this paper the simulation carried out for the electrical power 5 to 20 MWe. To reduce the heat transfer loss by the convection, the saline water is used MgCl2, NaHCO3 and NaCl respectively. The salinity of the different zones maintained as 0-5% in Surface Convective Zone/Upper Convective Zone (SCZ/UCZ), 5-20% in Non-Convective Zone/Gradient Zone (NCZ/GZ) and the concentration is almost like a saturated solution in the Lower Convective Zone/Storage Zone (LCZ/SZ). Due to different salinity in the SGSP, a temperature gradient and heat storage developed in the NCZ and LCZ respectively. The temperature developed in the storage zone will reach up to 1000 C using the corrugated bottom surface.
