Abstract

Sediment erosion not only reduces efficiency and life of hydropower turbines but also causes problems in operation and maintenance. Several factors are responsible for this erosion in hydro turbine components. This paper presents the sediment erosion types in hydraulic turbines and their components based upon an extensive literature review and the field observation at Cahua hydropower plant, Peru. It includes some recommended methods to minimize the effect of sediment erosion in the turbine components. An alternative design of a Francis turbine in sediment-laden water is also briefly discussed.
