摘要
现有的船闸输水廊道水力计算均未考虑水弹性作用。本文首次提出了考虑这种作用的计算方法,使之能模拟因阀门快速关闭而引起的廊道内的水击现象,从而为输水廊道的合理设计和优化运行提供了一种仿真性更高的数学模型。
The hydroelastical effect has not been considered in the current methods of mathematical analysis and computation for lock filling and emptying system desi'gn. A new numerical model which considers this effect is firstly presented in this paper. This model can be used to simulate the waterhammer phenomenon caused by fast valve closure during lock operation. It is demonstrated by some computational examples that the model not only can satisfy common calculation requirements, but also have high emulately simulative capability for lock filling and emptying operation. Thus, an effective numerical means is provided for lock filling and emptying system design and operation.
