Hydraulic Transients of Turbines: Hydroacoustic Modeling

This lecture covers the modeling of hydraulic turbines, focusing on topics such as specific speed, cavitation, yield hill, and turbine characteristics. It also delves into the stability of pump-turbines and the different modes of operation. The presentation includes detailed insights into the geometric characteristics of hydraulic machines and the considerations for reversible machines. Additionally, it explores the historical development of turbines post-World War II and the increasing demand for clean peak power production. The lecture concludes with a discussion on the selection criteria for Francis turbines and the importance of specific speed in turbine design.
