Numerical simulation of energy dissipator flow field for Shilianghe reservoir

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.
