小型海水太阳池实验及考虑浊度的温度分布模拟

建立了2.8 m×2.3 m×0.8 m小型太阳池,以卤水和溶解粗盐的海水灌注太阳池各层,进行了持续的池内温度和地表太阳辐射强度的测量.根据测定的气温和太阳辐射强度数据,考虑侧壁阴影部分对散射辐射的吸收,针对本太阳池进行了温度分布的逐时变化数值模拟.实验和计算结果表明,实验值和计算值吻合较好,保温性能较好的小型海水太阳池升温较快,适于在温度较高的月份用于供热.

Experiment in a small seawater solar pond and simulation of numerical temperature distribution considering turbidity

A small seawater solar pond with a dimension of 2.8 m×2.3 m×0.8 m was constructed. The pond was filled with bittern and the solution of coarse salt in water. The temperature in the pond and the radiation intensity during experimental period were measured. Based on the experimental data and the diffusive radiation absorbed by wall shadow, the temperature distribution in the pond with a one-dimension transient model considering the turbidity of the solar pond water was simulated. There is a better agreement on the experimental data and the simulating temperature distributions. Both the results suggest that temperature in the small solar pond with probably insulated rose up in short time, so it is better to extract heat in warm seasons.
