Modeling thermal-technical parameters of a solar pond using COMSOL multiphysics

The article presents the experiments of scientific study of the temperature changes of the pond layers at the given solar radiation values inside the solar pond device modeled using Comsol Multiphysics. The developed model of the solar pond with simplified geometry dimensions changes the sign of the experimental calculation in a positive direction, which helps to study and optimize the energy accumulation process. This research shows that computer modeling can be used to study and optimize the solar pond energy storage process. In addition, the results of this modeling can be used to improve the solar pond device and develop its new technologies. The models obtained from the 3D study of the process using the Comsol multiphysics program are analogs of the three-dimensional cross section in the vertical part of the solar pool. It has been shown that the bottom energy storage layer of the solar pool rises up to 60 ℃ when the concentration of the salt water mixture in the solar pool device varies around 25-30% and the energy storage reaches its maximum value when the solar radiation reaches its maximum value.
