Abstract

Pressure distribution around bottom outlet leaf gates and its role on the potential risk of cavitation, destructive vibrations of the gates, and to determine downpull forces have been the main importance tasks in the studies of outlet works of high dams. In this paper, regarding the importance of pressure distribution around bottom outlet leaf gates, a set of experiments were performed at Water Research Center of the Ministry of Iran Energy to determine the effect of the geometry of gate and flow conditions on pressure distribution around the gates. Experiments were based on physical model studies of a bottom outlet gate.
