The hydrostatic analysis showed an almost acceptable performance for the radial gate however, the hydrodynamic force, as a result of the MCL earthquake, imposes a 72% extra load on …

The phenomenon of hydrodynamic downpull caused by high flow velocities and reduced pressures beneath the gate, generates a downward force that can lead to structural failures …

The above findings show that to calculate the hydrodynamic pressure acting on a gate during an earthquake when performing earthquake response analysis of a gate, it is possible to calculate …

Mar 30, 2020 · The vertical lift gates are exposed to hydrodynamic forces that arise as a result of pressurized flow established by the large-scale effect of the water levels in the dam reservoirs.

These are hydrodynamic forces caused by the high-flow velocities under the gate, which creates a non-uniform pressure distribution on the surfaces of the gate, resulting in a downward vertical …

The numerically obtained hydrodynamic forces, hydraulic cylinder pressures and gate casing cover pressures are compared with physical measured data on site during the wet test of the …

Mar 10, 2016 · Forces were measured in trunnion bearing and in both hoists without restricting the movement of the model. Tailwater levels covered a wide range, representing the changed …

Aug 8, 2025 · This study aims to provide a deeper analysis of the mechanical effects induced by turbulent flow characteristics in the gate recess on the sector gate during dynamic water …

Dec 1, 2017 · As a result of gate openings, the downpull force is created from the difference between the downward force exerted by water passing over the top surface of gate and that …

Aug 29, 2021 · The extreme hydrodynamic force caused by ground acceleration, cavitation damage, and vibration are among concerns that threaten the safety of the spillway and its …
