摘要
建立了基于剖开算子法的沉淀池二维水流数学模型和悬浮物输移模型,应用改进特征线法和有限元方法耦合求解该数学模型,并利用实测资料对该模型进行了验证。验证结果表明该模型能够很好地模拟沉淀池中水流的流动以及示踪剂在池内的流动过程。
On the basis of operator-splitting algorithm, a mathematical model for predicting the velocity field and suspended solids transport in sedimentation tanks is developed. In the numerical solution algorithm, the method of characteristics, analytic method and Galerkin finite element method are chosen. The numerical results are also compared with experimental data. The results show that the mathematical model can well simulate the flow and the dye transport within the sedimentation tanks.
