以横丹水电站工程为例,基于κ-ε湍流模型封闭Reynods方程,采用VOF法追踪自由表面,通过有限体积法离散求解,数值模拟研究了低水头泄水建筑物的三种辅助消能方案,并分析了各自的水流特点和消能机理,以寻求一种安全可靠的消能工。
Taking Hengdan Hydropower Station as an example, the Reynods equation was closed based on the κ-ε turbulence model. The free surface was tracked by the VOF method. Three kinds of auxiliary energy dissipation schemes were studied by finite volume method and numerical simulation. The characteristics of water flow and energy dissipation are analyzed to find out a safe and reliable energy dissipater.
