A literature survey on silt erosion and cavitation in hydro turbine

Erosion of hydro turbine runner blades is a complicated phenomenon, this is depending on different parameters those are size of silt, cavitation, silt concentration, hardness of the silt particles, Different properties of base materials and operating hours. There are Several investigations have been studied the effect of these parameters on erosion. The turbine is most important part of hydroelectric power plant which converts the potential energy of water into mechanical energy. The high pressure of silt in water erodes the turbine material by impacting. Erosion of turbine reduces its performance, life span and as well as loss of power generation. This paper will provide a new approach of study of silt erosion of hydro turbine.
