CAVITATION EROSION IN FRANCIS TURBINES
Municipal economy of citiesThe phenomenon of secondary flow is a global problem that causes cavitation erosion in hydraulic equipment. Cavitation is a phenomenon of localised corrosion of the metal surface leading to instability and highly uneven flow behaviour with a consequent excessive noise, vibration, and decreased efficiency in Francis, Kaplan, and other turbines.

Flexible operation of Francis turbines
, 2023 With the planned cuts in emissions, more of the electric energy will have to come from renewable sources. Two of the largest potential sources are wind- and solar, which have the downside of also being intermittent and non-dispatchable. Since the electricity production must match the consumption, other energy producers in a grid must increase their ...
