Performance Evaluation of Pelton Turbine: A Review
Hydro Nepal: Journal of Water, Energy and Environment, 2014 Earlier only experimental techniques were used to predict the performance of turbines. With advanced numerical techniques and increase in processing power of computers, Computational Fluid Dynamics (CFD) has emerged as an effective tool for the performance prediction of Pelton hydraulic turbine involving multi-fluid flow.
