摘要
采用基于VOF自由面捕捉的全三维紊流数值模拟的方法,对琴键堰各个流量断面进行了泄流量的分析。通过比较五种不同堰高的琴键堰的泄流情况,分别从各个断面的流量所占的百分比、单宽流量和泄流效率等方面,得出了堰高对各断面的影响,从而得出了堰高越高泄流能力越强的结论,为今后的工程和研究提供参考。
With the method of VOF free-surface capturing-based full 3- D numerical simulation of turbulence,the discharges from all the discharge-sections of the piano-key weir are analyzed herein. Through the comparison among the discharges from five piano-key weirs with different heights,the impacts from the weir heights on all the discharge-sections are obtained from the aspects of the percentages of the discharges from all the sections,uinit-width discharges,discharge efficiencies,etc. respectively,thus it is concluded that the higher the weir height is,the stronger the discharge capcity is to be,and then a basis is laid for the study and construction of the relevant project.
