3D Dynamic Numerical Simulation of Water Flow in Stilling Basin with Flaring Gate Pier

Abstract:

3D numerical simulation is carried out for the water flow in stilling basin with X shaped flaring gate pier when the radial gate uses four different opening velocities. The space-time change law of hydraulic characteristics is obtained. The water level in the stilling basin is relatively higher while using lower opening velocities during the processes. The negative pressure exists on weir surface while the relative opening degree is less than 0.55; the maximal pressure on the slab of ogee section and stilling basin increases and moves to downstream with the gate opening. The results can provide important basis for shape optimization of practical engineering.
