Hydraulic turbines and their components operating in sediment-laden water are subject to abrasive and erosive wear. This wear not only reduces efficiency and life of hydro-power turbines but also causes problems in operation and maintenance. Several factors are responsible for this erosion in hydro turbine components. Numerical simulations of a prototype Francis turbine are carried out to investigate the influence of sediment characteristics on erosion prediction. Results from prototype inspection allow a qualitative validation of the simulations. The numerical predictions of erosion are based...
