    摘要:

    以典型平原河网地区上海市浦东新区拟建的赵家沟东泵闸工程为研究对象,分别采用准三维MIKE3 和仿真三维FLOW-3D 两种三维数值模拟软件对枢纽下泄水流流态进行模拟,并根据已有的平面二维MIKE21 模拟结果和物理模型试验结果,对两种软件三维水动力数值模拟结果的合理性进行分析。结果表明:准三维MIKE3 无法满足泵闸流态精细化模拟的需求,其模拟结果与物理模型试验结果存在差别,而仍与平面二维MIKE21 模拟结果类似;仿真三维FLOW-3D 模拟结果与物理模型试验结果接近,更加精细合理,可应用于类似水利工程设计研究中流态的精细化数值模拟。

    Abstract:

    Taking the Zhaojiagou East Sluice-Pump Project proposed to be built in the Pudong New District of Shanghai in a typical plain river network area as the research object, a quasi-3D numerical simulation software, MIKE3 and a real 3D software, FLOW-3D, were used to simulate the flow patterns of the discharge flow. The rationality of the simulation results of the two models were analyzed and compared based on the existing results of the horizontal 2D model MIKE21 and physical model test. The results show that, the quasi-3D MIKE3 cannot meet the requirements of the refined simulation of the flow pattern of the sluice-pimp project, and its simulation results are different from those of the physical model test, but still similar to those of the horizontal 2D model MIKE21. The results of the FLOW-3D are close to the results of the physical model test, which are more refined and reasonable, and can be applied to the refined numerical simulation of flow patterns in the design and research of similar water conservancy projects.
