Electricity is a renewable energy source that can be generated from natural energy resources. savonius rotor is a type of turbine which produces small-capacity electrical energy using the kinetic energy obtained in the water flow. The main driving force in this paper is to predict the hydrodynamic performance of elliptical blade savonius hydro turbines with computational fluid dynamics (CFD). A 3D unsteady simulation will be conducted using ANSYS-CFX 19. The elliptical blade profiles with vertical axis turbines are performed at different blade numbers of 2, 3, and 4 blades. The performance analysis results show an improvement in the coefficient performance value of the elliptical blade compared to the conventional semi-circular blade. Based on the results, the more appropriate results obtained at TSR 1.069 for three elliptical blades with a power coefficient value of 0.738.
