| 摘 要： | 沿程能量损失和水流动能的变化引起V型滤池配水渠水面高程沿程变化,造成滤池配水的不均匀.基于流体力学基本原理,推导出配水渠内水面升降的计算公式,并做了配水均匀性的定量分析.根据配水渠内水面高程的变化容易算出各配水堰顶高程的调整量,按此方法调整配水堰顶高程,可显著改善滤池配水的均匀性

| Abstract: | The water level of distribution trench of V shape filter fluctuates with the frictional energy lossed and changed of flow velocity energy. These cause filter distribution asymmetry. Based on hydromechanics principles, deduced calculating formulas and made a quantitative analysis of distributing uniformity. According to the fluctuation of water level in distribution trench, it was easy to reckon the value of adjusting weir peak level, and to regulate it to remarkably improve distributing uniformity of filter. |
