摘要
在水利工程建设中,设计科学合理的消能防冲设施具有重要意义,是工程安全稳定运行的必要保证。本文以具体工程为背景,利用数值模拟的方式探讨了底坎对嵌槽消力池消能效果的影响。试验结果显示,在嵌槽下游设置底坎有助于降低消力池内流速,提高消力池的消能率,并根据计算结果得出了最佳方案,该研究为相关工程设计提供支持和借鉴。
In the construction of water conservancy project,it is of great significance to design scientific and reasonable energy dissipation facilities,which is the necessary guarantee for the safe and stable operation of the project.In this paper,the influence of base sill on the energy dissipation of slotted stilling pool is discussed by numerical simulation.The test results show that setting the base sill in the downstream of the inlaid tank is helpful to reduce the flow rate in the stilling pool and improve the energy dissipation rate of the stilling pool.The optimal scheme is obtained according to the calculation results,which can provide support and reference for related project design.
