Abstract

Based on establishing the computational fluid domainÿof underflow vertical lift gate under different openings, the 3D numerical simulation is carried out by a combination of VOF model and standard - model to predict the distribution of flow velocity, pressure and turbulence kinetic energy. The results show that there are different sizes of vortexes in the downstream of the gate due to flow separation from the gate bottom edge. The smaller the gate opening is, the greater the flow velocity underneath the gate is, and the further away from the gate the vortex structure is. Turbulent kinetic energy decreases with the increasing of gate openings and impacts the flow state in the vicinity of gate. The smaller the opening is, the greater the pressure difference between the upstream and downstream of the gate is. The negative pressure mainly appears on the downstream of the gate. Appropriate increasing the gate opening is conducive to the safe and stable operation of the gate.
