摘要
应用液体连续性方程和能量方程讨论了活动堰水力计算原理 ,采用边界层理论分析了水流流经活动堰的水头损失 ,并编写了流量计算程序 .通过对活动堰测流进行实验研究和理论分析 ,认为活动堰过流的淹没度限值高 ,理论计算流量精度满足测流要求 .
The continuity equation and the energy equation are applied to investigation of the theory of hydraulic computation of movable weir. And theory of boundary layer is applied to illustrating the head loss of water flowing through movable weirs. Then it is programmed in Fortran language. Experiment and analysis of movable weir for flow measurement indicate that the modular limit of movable weir is relatively high. And the accuracy of theoretical discharge calculated is satisfied.
