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 ...

Sediment erosion in Francis turbines
, 2009 Sediment erosion is a major challenge for run-of-river power plants, especially during flood periods. Due to the high content of hard minerals such as quartz and feldspar carried in the river, substantial damage is observed on the turbine components. Material is gradually removed, thus the efficiency of the turbine decreases and the operating time of ...
