Equilibrium Chimney and Mass Oscillations

This lecture covers the concept of equilibrium chimney and mass oscillations in the context of hydroacoustics for hydroelectric installations. It discusses the risks associated with equilibrium chimneys, such as overflow, diaphragm cavitation, and resonance with the regulator. The presentation includes details on the types of chimneys, the modeling of mass oscillations, and the sizing of equilibrium chimneys. Additionally, it explores the impact of closing time on chimney levels and the behavior of the system during emergencies. The lecture also delves into the analytical resolution of chimney oscillations and the calculation of various physical parameters and integration parameters.
