چکیده مقاله Evluation of pressure distribution arround the high-pressure gates

Bottom outlets are side structures of dams used for supplying downstream water and managing flooddrainage. Two service and emergency gates usually regulate the output flow rate. Estimating thepressure on these gates is crucial for cavitation risk from negative pressures and evaluating the force onthe gates due to the lifting jack design. This force increases with head height and the flow speed in thegates. To calculate the gates lifting force, an appropriate safety factor should be applied, because itsignificantly impacts the vibration of the gates and related equipment like lifting jacks. This researchinvestigates the pressure distribution around bottom sliding outlets using 10 different dam laboratorymodels and analyzes the factors influencing this pressure distribution.
