| 摘 要： | 通过物理模型试验及推导建立植物过流水动力学方程，对植物“柔性坝”过流时的水动力学特性进行了数值研究；利用计算流体力学软件FLUENT，用VOF方法追踪自由水面，采用多孔介质域模拟植物坝覆盖区域，以多孔介质前后压强配合空隙率来确定渗透率，对有植物坝覆盖的水槽二维两相流场进行了数值模拟。将数值计算得到的流速值与模型试验流速值实测结果进行了比对，两者吻合较好。 |

| Abstract: | In this paper, the hydrodynamic equation about the flow through plants has established through the physical model experiment and theory deducement, and the hydraulic characteristics of vegetation dam has simulated with the established equation. And the two-phase flow field of the water sink with plant dam overlay has simulated with CFD software FLUENT, and the free surface has been tracked with VOF method, the plant dam overlay districts has been simplified with many bores area method, and the infiltration rate has been determined with the pressure difference of before or after bores area. And the simulation velocity magnitude are compared well with the measured data. |
