Erosive wear of hydro turbine runners depends upon different parameters such as size, hardness and concentration of silt particles, velocity of flow, properties of the base material of the turbine components and operating hours of the turbine. Various researchers have conducted experiments to...

In the present study, an experiment was carried out to investigate the mechanism of erosion of a small scale Pelton turbine, under actual flow conditions. Samples of silt were collected from the head work of one of the most silt affected hydro power station in India. Silt parameters (silt...

The erosion of turbine components causes the decrease in turbine efficiency; increase in the maintenance cost and down time for turbine repair. All these factors contribute to the plant cost and cause the revenue losses. It is, therefore, essential to study the amount of efficiency loss owing to...
