Hydrodynamic forces during the operation of a model radial gate
A 1:17 scale physical hydraulic model of a radial gate was employed to determine forces during the lifting and lowering of the gate with rates from 0.1 to 1.1 m/min for prototype (current operating rate is 0.1 m/min), and to determine the combinations of discharge, gate opening and tailwater level that cause instability of the gate. 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 conditions after the completion of the downstream dam. The study indicated certain trends regarding the instability of the gate, and showed that the current rate of raising the gates could be significantly increased, providing safer operation of the whole system during some specific operating conditions.
