Savonius Rotor Design
The Savonius rotor is a simple yet effective design for vertical axis wind turbines. It consists of two or more curved blades that capture wind energy from any direction. You'll find this design particularly suitable for low-wind areas and urban environments due to its ability to start at low wind speeds.
To build a Savonius rotor, you'll need to create S-shaped or semicircular blades. These can be made from inexpensive materials like PVC pipes cut lengthwise or repurposed metal drums. The blades are mounted vertically on a central shaft, with each blade's concave side facing the wind.
The rotor's operation relies on the difference in drag between the concave and convex sides of the blades. As wind hits the concave side, it creates more force than on the convex side, causing the rotor to spin. This simple mechanism makes Savonius rotors ideal for DIY projects.
When designing your Savonius rotor, consider the following factors: blade curvature, aspect ratio (height to diameter), overlap between blades, and end plates. These elements will affect your turbine's efficiency and power output.
Experiment with different configurations to optimize performance for your specific location and wind conditions.
Darrieus H-Type Turbine
You'll find the Darrieus H-Type turbine offers a unique approach to vertical axis wind power.
