Load Behavior of an Vertical Axle Wind Turbine Model With a Four Blades Periodically Coupled Aerodynamically
Keywords:
Savonius rotor, low wind, wind tunnel
Abstract
The paper is based on experiments conducted on the wind tunnel at low wind speeds (<4.5 m/s), on an experimental wind turbine model of the Savonius type with four blades and a D/H ratio of 2.6. The four blades are periodically coupled aerodynamically. The model acted a DC generator with a speed multiplier. Experiments were performed by modifying the generator electrical charge. The results confirm the validity of the concept proposed.
