摘要
针对盐梯度太阳池的盐度和浊度,采用实验与理论分析相结合的方法进行研究。通过建立小型太阳池,得到了不同盐梯度下太阳池各对流层温度曲线;从光学的角度进行理论分析,并与实验数据对比,结果表明:温度变化率随太阳池深度增加而增加,温度变化率在下对流层深度的2/5~3/5处最大;非对流层浊度随盐度、悬浮颗粒粒径及数量增大而增大;太阳池的升温速率与保温性随盐度与浊度的增大而增大,盐度与浊度可以提高下对流层储热性能。
The method of combing experiment and theoretical analysis was used to study the salinity and turbidity in the salt gradients solar pond.The temperature curves of the troposphere in the solar pond under different salt gradients were obtained by establishing a small solar pond.From the optical point of view,theoretical analysis results were compared with experiment data.The results show that the temperature change rate increases with the depth of the solar pond,and the temperature change rate is the largest at 2/5~3/5 of the depth of the lower-convective zone.Non-convective zone turbidity increases with salinity,suspended particle size and number.Both the heating rate and thermal insulation of the solar pond increase with the increase of salinity and turbidity,the heat storage performance of lower-convective zone can be improved by salinity and turbidity.
