摘要
盐梯度海水太阳池具有收集和贮存太阳能的双重功能.为了满足太阳池研究计算的需要,建立了海水太阳池的二维轴对称模型,对太阳池内的温度场进行了模拟计算,并与实验数据进行了对比.通过比较发现,采用W.S.模型,其数值结果和实测值比较吻合;太阳池面积和浊度对太阳池热行为有很大影响,应用二维模拟计算,可确定简化为一维模型的太阳池的最小面积为300m2.
The salt-gradient seawater solar pond has the dual functions in collecting and reserving solar energy. In order to satisfy the demand of studying the solar pond, a two-dimensional model of solar pond is presented and the temperature field of the pond is numerically simulated which is analyzed and compared with experimental data. And it is concluded that using the W.S. model, the results of the numerical simulation agree better with the data of the experiment. The area of the solar pond and turbidity have distinct effects on the thermal performances of the solar pond. Using the two-dimensional model, the minimum area of the solar pond over which the ponds can be simulated by simplified one-dimensional model with sufficient accuracy is 300 m^2.
