  • In this thesis hydraulic experimental studies and theoretical analyses on the vortex - flow drop shaft were conduced and the following results were accomplished : ( 1 ) in the model test some hydraulic characteristics including the shape of air core in the center of the drop shaft , the radial distribution of water flow velocity and the distribution of pressure on the wall of the drop shaft were measured under the condition of high water head above 250m and large discharge above 1400m3 / s . ( 2 ) a kind of computational method for the spiral water flow in the air core region of drop shaft was discussed and applied and the results agree the experimental data well . ( 3 ) the total ratio of energy dissipation in the drop shaft can reach 90 % and the energy dissipation in every region was discussed quantitatively
    本文通过试验研究与理论分析对旋流式竖井泄洪洞应用于高水头、大泄流量情况时存在的一些水力学问题进行了研究和探讨,取得以下主要成果:一、结合小湾工程导流洞改建,对高水头( 252m ) 、大泄流量( 1400m ~ 3 s )条件下旋流式竖井中的水流运动特征进行了比较全面的测量,包括空腔形态、径向流速分布及井壁压强等;二、提出了竖井空腔段螺旋水流水力计算方法,其计算结果与实测值吻合良好;三、利用试验与计算结果,对旋流式竖井的消能机理进行了探讨,对竖井各部分的消能能力有了总体认识;四、对竖井下部消力井的合理井深进行了优化试验研究,发现消力井合理深度为0 . 9d左右;五、通过试验研究,归纳出竖井水流总掺气量估算方法,为导流洞排气方案的设计提供了参考依据;六、在高水头、大流量条件下,竖井空腔段下部流速很高,尽管水流螺旋运动引起的离心力可以确保井壁压强保持正压,但空化数依然较低,因此竖井的空化空蚀始终是工程界关注的重大问题。
