Performance Study of Modified Savonius Water Turbine …

Savonius rotor is a vertical axis rotor with simple in design and easy to fabricate at lower cost. The rotation of the rotor is due to the drag difference between the advancing blade and returning blade. Net driving force can be increased by reducing the reverse force on the returning blade or increasing the positive force on the advancing blade.

Vertical Axis Wind Turbine

Looking downward from the top, a turbine with a Savonius rotor would look like two spoons facing opposite directions and linked at the center to the rotor axis (creating an ''S'' shape in cross section (Fig. 20.14)).Due to their curvature, the drag of the concave surface is higher than the convex surface, forcing the rotor to turn when the cups are exposed to wind (Mathew, 2006).
