摘要/Abstract

摘要： 针对船闸闸底长廊道侧支孔输水系统，通过改变消力槛高度和消力槛距侧支孔距离，采用三维紊流数值模拟方法，研究了消力槛对闸室单明沟消能的影响特征。研究结果表明：在单明沟内增设一道消力槛后的消能效果优于无消力槛方案，且当消力槛高度为侧支孔高度的一半，消力槛距侧支孔距离为明沟宽度的0.4~0.6倍时闸室内消能效果较佳。同时阐明了单明沟与消力槛的协同消能机理。

Abstract: For the filling/empty system of the side branch hole of the long corridor at the bottom of the ship lock, the three-dimensional turbulence flow numerical simulation method was adopted to systematically study the influence characteristics of the dissipating sill on the energy dissipation of a single open ditch in the lock chamber by changing the height of the dissipating sill and the distance between the dissipating sill and the side branch hole. The research results show that the energy dissipation effect after adding a baffle sill within the single open ditch is better than that of without any baffle sills; moreover, when the height of the dissipation sill is half of the height of the side support hole, and the distance between the dissipation sill and the side support hole is 0.4~0.6 times the width of the open ditch, the energy dissipation effect in the lock chamber is better. Meanwhile, the synergistic energy dissipation mechanism of a single open ditch and a dissipation sill is elucidated.

Key words: waterway engineering; ship lock; filling/empty system; open ditch; baffle sill; energy dissipation characteristics
