Investigation of the Erosion Characteristics in the Distribution Parts of Pelton Turbine

Pelton turbine, as its working principle, can perform in the high head condition especially in the southwest mountainous region in China. When the flow contains silt, it will induce the erosion in the bucket and needle structure which affects the efficiency and furthermore the service life. This pap...
