石梁河水库消力池强紊动水流的数值模拟

Numerical simulation of energy dissipator flow field for Shilianghe reservoir

  • 摘要: 采用半隐式的控制体积法离散紊流控制方程,考虑曲率修正的双方程紊流模型封闭雷诺应力,引入通度和体积函数的概念,数值模拟了石梁河水库工程改建后两级消力池的泄流过程.计算结果给出了自由表面的演变过程及其相互碰撞、重叠的消力池水流特征,断面流速、压力分布及自由水面位置与物理模型试验结果吻合良好.

     

    Abstract: Energy dissipator flow is a kind of strong turbulent two dimensional flow with unsteady free surface.In this paper,a double-equation model incorporating the method of curvature correction is developed to closure the Reynolds stress and the SIMPLEC scheme is used to discrete turbulent governing equation.The numerical model is applied to simulate the Shilianghe project energy dissipator unsteady flow field.The computed results give out rational characteristics of turbulence-vortex and bumping of free surface,are agrees with the experimental results,and show that the model is effective and practical to solve similar engineering problems.
