The abrasive action of these particles causes the hydro turbines to suffer from erosion in particular at high- and medium-head hydroelectric power plants. This has become a serious economic issue ...

However, the physical mechanism of hydro-abrasive erosion in Pelton turbine buckets is still not well understood as the cumulative erosion is changing with the transient flow in rotating buckets. In this work, a new approach to predict the cumulative erosion on a rotating surface is proposed and applied to Pelton turbine buckets. ...

The amount of erosion depends on a number of factors: the quantity of debris, the type of debris, turbine material and the location of the part [1]. Often the worst erosion occurs on high head turbines like Peltons. Where the water is moving very quickly through the spear valve, erosion can result in tracks being cut into the surface of the spear.

In their reviews of hydro-abrasive erosion of hydraulic turbines, Padhy and Saini [11] and Felix et al. [12] listed the parts of Pelton components mainly affected by this phenomenon, namely needle tips, seat rings and injector nozzles, runner buckets, jet deflector, protection roof of injectors, casing, and grating below runner. However, the ...

This thesis examines sediment erosion in hydro turbines. A number of factors influence sediment erosion damage, including the sediment characteristics, turbine design and operating conditions, and materials used. Laboratory experiments and numerical simulations were conducted to better understand particle motion and separation within turbines. The simulations predicted erosion …
