摘要: 输水渠道中的水位将随流量的改变而产生波动,且由一种恒定流状态过渡到另一种恒定流状态需要经过一段稳定的时间。这一水力变化过程与渠道自身的结构特性、渠道运行方式的选择和流量变化的幅度、速率有关。通过对渠道中的非恒定流进行数值模拟,对不同情况下渠道的水力学响应进行了研究。

Abstract: Water levels in open channel fluctuate along with the change of the discharge. The change from one state of steady flow to another will take a period of time. The process of the change is affected by the characteristic of canal structure,the canal operation method,the range of discharge change and the rate of it. The hydraulic reaction of unsteady flow is also studied by means of numerical simulation of the unsteady flows in open channel in different cases.
