Hydrodynamic self-excited vibrations in leaking spherical valves with annular seal

Occasionally, annular seals of ball valves in hydro power plants may not perform their sealing function adequately but develop periodic vibration with periodic leakage rates causing high amplitude pressure fluctuations in the penstocks. The aim of the present study is to develop a simplified model t...
