Improved performances of the wind inlet of the Savonius rotor [PDF]

open access: yesVojnotehnicki glasnik, 2017
In this study we analyzed the design changes through increasing vertical angles of the top and bottom plates of the wind inlet of a Savonius rotor, in order to obtain better results and better system performances. A designed wind inlet is placed in the front part of the rotor in order to prevent negative torque opposing rotor rotation.

CFD computation of the Savonius rotor

open access: yesJournal of Theoretical and Applied Mechanics, 2015
In this paper, Computational Fluid Dynamics (CFD) analysis of a two-dimensional two- -bucket Savonius rotor, using ANSYS Fluent solver, is presented. Computational methods of fluid dynamics are used to estimate the aerodynamic forces acting on the rotor, the torque and the power extracted by the Savonius rotor.

Experimental Study of Darrieus-Savonius Water Turbine with Deflector: Effect of Deflector on the Performance

open access: yesInternational Journal of Rotating Machinery, 2014
The reverse force on the returning blade of a water turbine can be reduced by setting a deflector on the returning blade side of a rotor. The deflector configuration can also concentrate the flow which passes through the rotor so that the torque and the ...
