A New Approach for the Study of Silt Erosion of Hydro Turbine
نویسندگان
چکیده
Turbine is the most important part of hydro power plant which converts the potential energy of water into mechanical energy. The presence of silt in water erodes the turbine material. Erosion of turbine decreases the performance of turbine, life of the turbine as well as loss of power generation. This paper presents a new approach for the study of silt erosion of hydro turbine. In this study, weight of eroded material of turbine have been determined by employing criterion of plastic strain which include parameters (silt size, silt hardness, concentration of silt, flow velocity, hardness of turbine material) affecting silt erosion of turbine. Results have been verified with experimental work for Pelton turbine having 16 buckets made up of brass material. It is seen that the results of analytical study matches with the experimental work. Keywordssilt erosion, plastic strain, hydro turbine, Silt effecting parameter and Mass loss.
