A numerical method is applied here to simulate the unstable flow and the vibration of a plane gate. A combination of the large eddy simulation (LES) method and the volume of fluid (VOF) model is used to predict the three-dimensional flow field in the vicinity of a plane gate with submerged discharge. The water surface profile, the streamline diagrams, the distribution of turbulent kinetic energy, the power spectrum density curve of the fluctuating pressure coefficient at typical points underneath the gate, and the complete vortex distribution around the gate are obtained by LES-VOF numerical calculation. The vibration parameters of the gate are calculated by the fluid-structure coupling interface transferring the hydrodynamic load. A simultaneous sampling experiment is performed to verify the validity of the algorithm. The calculated results are then compared with experimental data. The difference between the two is acceptable and the conclusions are consistent. In addition, the influence of the vortex in the slot on the flow field and the vibration of the gate are investigated. It is feasible to replace the experiment with the fluid-structure coupling computational method, which is useful for studying the flow-induced vibration mechanism of plane gates.

Based on establishing the computational fluid domain of underflow vertical lift gate under different openings, the 3D numerical simulation is carried out by a combination of VOF model and standard κ-ε 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.
