An assessment of sediment erosion on Pelton buckets using CFD

The northern Himalayan region of India has rivers that are full of sediments with mineral composition consisting of quartz, feldspar, hornblende and mica. This causes extraordinary damage to the turbine blades resulting in frequent maintenance issues and intermittent shutdowns resulting in economic losses. This paper presents a case study of the Chenani power station, and the modelling of sediment erosion on Pelton buckets there while also providing information for consideration in the future development of turbine buckets.
