摘要
针对宽浅河道水流的特点,建立了一个基于分层积分降维数值解法的三维浅水紊流数值模型。通过对弯道水流的验证计算,其计算成果和试验值能较好地吻合。笔者等建立的数学摸型特别适合用来解决宽浅河道及河口水流问题。
A three-dimensional numerical model for shallow flow based on a layer-integrated solution method is developed in this paper.The controlled equations are solved using an efficient operator-splitting finite element method on adaptive triangle grids.The experiment data in mending channel flow is selected to verify the proposed model.The simulated results are in satisfactory agreement with the experimental data.Therefore,the present 3D shallow flow model is a robust and efficient tool for simulating the shallow flow hydrodynamics.
