Numerical Simulation of Double-diffusive Dynamical Model of a Solar Pond Considering the Effect of Turbidity and Wind

一个太阳的池溏，典型双 diffusive 系统，是能收集并且存储太阳能的稳定的热来源。当热稳定的条件没在接口满足时，上面、更低的对流地区(UCZ 和 LCZ ) 将侵蚀中间的非对流的地区(NCZ ) ，导致落下或甚至太阳的池溏的热性能的倒塌。风强烈从 UCZ 的乘火车影响 NCZ 的侵蚀。热和盐的双散开从降低对流的地区(LCZ ) 的乘火车在 NCZ 的侵蚀起一个重要作用。池溏里的盐的水的混浊不仅能降低太阳的池溏的热表演，但是在乘火车机制上有效果。在这份报纸，基于与风驱动的狂暴的乘火车模型一起的双 diffusive 模型，太阳的池溏和乘火车机制的热表演上的混浊和外部风等等的效果与数字模拟被分析。关键词太阳的池溏 - 弯屈 - 双散开 - 混浊 - 侵蚀 CLC 数字

A solar pond, typical double-diffusive system, is a stable heat source that can collect and store the solar energy. When the thermal stable condition is not satisfied at the interface, the upper and lower convective zone （UCZ and LCZ） will erode the middle non-convective zone （NCZ）, resulting in a drop or even a collapse of the thermal performance of solar pond. Wind strongly affects the erosion of NCZ from the entrainment of UCZ. The double-diffusion of heat and salt plays an important role in the erosion of NCZ from the entrainment of the lower-convective zone （LCZ）. The turbidity of saline water in the pond not only could lower the thermal performance of solar pond, but have effect on the entrainment mechanism. In this paper, based on the double-diffusive model along with the wind-driven turbulent entrainment model, the effects of turbidity and external wind etc. on the thermal performance of solar pond and the entrainment mechanism are analyzed with the numerical simulation.
