Abstract:
High-head gates in dams and outlet works, was the principal concern of the investigation. The geometrical configuration chosen for the study is a highly idealized representation of a flat-bottomed, high-head gate just protruding into the flow--in effect, a normal wall or step. The primary objectives of the research were to investigate how basic flow instabilities associated with a free shear layer may lead to flow-induced vibrations of high-head gates, and to relate the mechanisms elucidated by the study of the idealized gate geometry to a general classification of flow-induced excitation.
