STUDY OF HEAT AND MASS TRANSFER IN A SMALL SCALE BITTERN-SEAWATER SOLAR POND
A low-cost small-scale solar pond filled with bittern and seawater was constructed in Dalian, China. An experimental and theoretical investigation of temperature as well as salinity evolution in the test solar pond is presented. A two-dimensional transient conductive model was used to predict the temperature evolution of the pond, and a one-dimensional mass transfer model numerically simulated the salinity diffusive problem. The effects due to the shading area of vertical wall, the pond depth as well as the hourly variation of the solar radiation and the air temperature during a year have been taken into account. The experimental temperature profiles show that the mean temperature of LCZ reached its maximum value of nearly 45℃ on the 17th day after operating. Results of this work show that the solar pond filled with seawater and bittern is suitable for establishing salt gradient solar pond to collect and store solar energy.
