Numerical Simulation of Shallow Solar Pond Operating Under Open and Closed Cycle Modes to Extract Heat, in the Medea Area, Algeria

Abstract

The aim of this work is to do a numerical simulation to study the thermal performance of a shallow solar pond operating under open and closed cycle mode of heat extraction. The pond is equipped with two glass covers and a surface equal to 1 (m2) (1.3 m * 0.76 m). The bottom of the pond is painted black to increase the absorption of solar radiation. It is also equipped with a serpentine to extract heat through the heat-carrying fluid represented by water. taking into account the climatic and geographical conditions of the region of Medea by date 80/08/2019, and based on the differential equation solutions resulting from the pond heat balance equations, and by using the MATLAB software, a numerical code was developed to perform a numerical simulation To predict the temperature of the various components of the pond, The results obtained showed an increase in the temperature of the pond water and the temperature of the heat transfer fluid during closed mode 10.4173% and 11.5926% respectively, this compared to the open cycle mode.
