Spectral calculation of thermal performance of solar pond and comparison of the results with the experiments
This paper deals with the method and the result of the spectroscopic calculation on the heat balance of a salt-gradient solar pond under the conditions of spectral solar radiation. Furthermore, the reflection of the rays incident upon the surface of the pond water, the refraction of the rays within the salt water layer and the diffusion of the salt in the pond water are considered. On the other hand, in order to make clear the mechanism of heat collection and heat storage of a solar pond, the authors conducted the indoor experiment and numerical analysis on a small scale model of salt-gradient solar pond with 2 m{sup 2} surface area and 1.6 m depth, under incident ray from a Xe-lamp solar simulator. According to above experimental analysis, the authors made a simulation model of thermal performance for a solar pond and calculated the heat balance in it. They found that the simulation calculations correspond well to the experimental result, so that their thermal simulation model might be correct. Furthermore, the authors also did the thermal calculation by changing the incident ray from Xe-lamp into natural ray, and found that the temperature distributions were notably different due to spectral characteristics of the incident ray. Therefore, the spectroscopic consideration for thermal performance of any solar pond is necessary to obtain a correct solution under the spectral incidence of special distributions.
