Hydro-Abrasive Erosion Of Pelton Turbine Injectors

Hydro-turbines often suffer damage caused by the presence of suspended sediment in the water flow. The solids hit the turbine components causing a removal of material from their surfaces, a phenomenon generally known as “hydro-abrasive erosion” (or “wear”). The issue is particularly relevant in world regions where rivers are seasonally or permanently rich in sediments,
