Savonius type wind turbine (flow near the deflecting plate and rotors)

摘要

A wind concentrator with eight guide vanes increases the efficiency of the Savonius wind turbine. The optimal rotor shape for the concentrator is found by experimental study. When there is only one guide vane, it is called a deflecting plate. The shape of the deflecting plate that increases the efficiency of the Savonius wind turbine (flat plate placed perpendicular to the flow) is found by an experimental study. This report shows the flow near the deflecting plate. A separating area produced by the deflecting plate placed perpendicular to the main flow covers the returning rotor. When it has a short plate at one side (L-type), and when the deflecting plate is placed obliquely, a flow toward the returning rotor appears.
