摘要:
为研究循环单井地下水流动机理,引入渗流-管流耦合模型,建立了循环单井地下水多流态流动的统一数学模型,并通过数值模拟与试验结果相比较验证了模型的正确性。该模型将流量边界移至井口,并将井孔壁的流入流出边界转换为求解区域,避免了流量大小和分布的预先给定。应用该模型对一典型循环单井的地下水流动特性进行了模拟计算,结果表明:循环单井运行时,含水层上部产生回灌效应,下部产生抽水效应,地下水通过井孔壁与含水层进行质量交换,算例中循环单井的原水交换比达到29.6%。
Abstract:
To research the groundwater flow mechanisms of standing column well(SCW),the uniform mathematical model of the groundwater multi-pattern flow in SCW is established by introducing coupled seepage-pipe model.The correctness of the model is validated via comparison of the numerical simulations with the experimental results.In this model,the flow boundary conditions are moved to the wellhead,and the boundary of flow-in or flow-out at the borehole wall is transferred to the calculation region.The flow distribution at the borehole wall doesn’t need to pre-set.A numerical simulation is made on a typical SCW applying this mathematic model.The results show that there is a recharging effect in the upper aquifer and a pumping effect in the lower aquifer,and the groundwater exchange occurs in the borehole and local aquifer via the borehole wall when a SCW is operated.The ratio for original groundwater exchange achieves 29.6% in this sample case.
