This is an intensive, one week course on the fundamentals of cavitation and its consequences in the operation of hydropower projects. The course will cover the factors that contribute to cavitation, including turbine design, operation, turbine setting, and other factors such as surface roughness and water quality.
The topics to be covered include a review of turbomachinery fundamentals and cavitation principles. The discussion of cavitation principles will include factors leading to cavitation inception such as boundary shape, turbulence, secondary flow patterns, dissolved gas and nuclei content of the water. The features of cavitating flows that lead to erosion, noise and vibration will also be discussed.
