本文用有限元法分析了污水处理过程中二沉池内的非定常流动方程。对应于这种液-固流动的模型是高度非线性和耦合的，并且包含湍流的影响。将数值模拟结果与全尺寸沉淀池试验的实验结果以及基于理想化一维通量理论的有限差分程序的结果进行了比较。在模型的适用范围内，计算结果与试验结果吻合较好。版权所有© 2005年约翰威利父子有限公司。
The equations governing unsteady flows in secondary settling tanks, a component of the wastewater treatment process, are analysed using the finite element method. The model corresponding to such liquid–solid flows is highly non‐linear and coupled, and incorporates the effects of turbulence. The results of numerical simulations are compared against experimental results from tests on full‐scale settling tanks, and against results obtained from a finite difference code based on an idealized one‐dimensional flux theory. The results compare well with the test results, over the range of applicability of the model. Copyright © 2005 John Wiley & Sons, Ltd.
