International 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 ...

Performance of Savonius Rotor with Slits in the Blades.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1993 This paper is focused on the improvement of the performance of the Savonius rotor. For this purpose, the flow inside and outside the rotor is observed by means of a flow visualization method. The behavior of the vortices shed from both sides of the rotor is measured by means of hot-wire flow velocity meters.

Aerodynamic Loads on a Stationary Savonius Rotor
JSME international journal. Ser. 2, Fluids engineering, heat transfer, power, combustion, thermophysical properties, 1991 The discrete vortex method was used to provide detailed information on the flowfield and starting torque on a stationary Savonius rotor. The rotor position normal to the wind was selected to examine the local flow properties on and around its ...
