WebNov 5, 2024 · Sluice gates are commonly used in canals for control and measurement of the flow. The discharge under sluice gates can be determined through different discharge methods. WebThese parameters were used in the orifice flow formula to calculate the flow rate.【Result】The critical ratio of orifice flow to weir flow was close to 1, the Froude number was uniformly distributed along the flow path, and the average relative head loss across the gate was 7%.

WebApr 10, 2024 · In most sluice gate models, the energy losses are assumed negligible; however, Habibzadeh et al. reported that turbulence-related phenomena cause significant energy losses in the submerged-flow condition. Additionally, the recirculating region below the gate induces turbulence that results in energy loss in the upstream pool.
