A mathematical modeling of the insulated cylindrical model solar ponds

Artificial solar ponds are saline water ponds that are about 1.5-3 m in depth and contain salty water in increasing intensity. Solar ponds are generally comprise of three zones. These are upper convective, non convective and bottom convective zones. Upper convective zone is composed of fresh water. Non convective zone is insulated zone which contains different density salty water that increase in downward, and bottom convective zone contains highly intensity solar water that stores and absorbs solar energy. In this system, heat insulation methods are very importmant to keep the heat in the storage zone for along time. Furthermore, coating of the side walls of the system with a heat insulation material and minimizing heat losses is important for the performance of this systems. In this thesis work, heat loss of our system for each month through 12 months have been analyzed and modeled by using the Heat 2 software. As a results, total heat loss in side walls and inner insulation zone of the system was found respectively 1286.47 W and 6163.34 W for a year
