3D Dynamic Numerical Simulation of Water-Air Two-Phase Flow of Flaring Gate Pier and Stilling Pool

Abstract:

The RNG k-e model and dynamic mesh technology are applied to simulate the unsteady flow of flaring gate pier and stilling pool during the process of radial gate opening. The space-time change law of hydraulic characteristics is obtained. The negative pressure exists on weir surface while the relative opening degree (e) is less than 0.3; the maximum pressure on the slab of stilling pool increases and moves to downstream with the gate opening; the velocity near the slab is relatively larger in the foreside of stilling pool and reaches the maximum value at e=0.5. The numerical results agree well with the experimental data, which shows the method is effective and can provide reference for shape optimization of practical engineering.
