地下含水层储能的实验分析与模拟

Experiment and Simulation on the processes of Aquifer's Thermal Energy Storage

以达西定律为理论基础,建立了模拟地下含水层储能真实环境的实验平台和模拟程序,通过实验数据和模拟程序的拟合,模拟真实环境的地下含水层温度分布和水流运移;以及回灌热水在实验台中流动和传热情况,发现回灌水对含水层的直接影响区域较小,含水层中水的横向流动和传热较为缓慢;含水层中垂向流动和热传递很小,各层间的相互影响作用较小。

Energy saving is one difficulty of technology,and aquifer thermal energy storage （ATES） is one of new sanitary technology, which is energy saving, agelong and accords the development of society. Based on the theory of Darcy＇s law, the author builds a experiment equipment that can simulates the real situation, and designs a program. The result of experiment and the result of program are same, so we can know that the experiment equipment can reflect distribution of temperature and that this program is useful and able to simulate the temperature＇s distribution of the whole Shanghai area. By filling heat water and researching its flowing and passing heat in the experiment equipment, the paper can get some useful and practical conclusions. In the aquifer, the infection area of filled heat water is small, flowing and passing heat on landscape orientation are both slow; and flowing and passing heat on upright orientation are both slow too, so infection between layers is little.
