Cavitation in hydraulic turbines occurs when the pressure in a fluid falls below its vapor pressure, leading to the formation of vapor bubbles within the fluid. These bubbles can collapse violently when they move to a region of higher pressure, causing shock waves that may damage the turbine blades and components. Furthermore, cavitation can lead to reduced efficiency, vibrations, and a decrease in the lifespan of the machinery.

Examples of cavitation-induced damage include pitting on the turbine blades, noise, and reduced throughput. It is critical to design and operate hydraulic turbines in such a way as to minimize the occurrence of cavitation.

For a detailed understanding of the impact of cavitation and how to mitigate it, please refer to:

I've observed similar effects in pumps. Are the mitigation strategies for turbines and pumps similar?
