Spiral wind turbine blades

What is Archimedes spiral wind turbine?

5. Conclusion Archimedes Spiral Wind Turbine (ASWT) is a new wind turbine design to extract kinetic energy from the wind. In the current work, a deep comparison between two different blades designs, fixed and variable angle blades, of the ASWT is introduced.

Does blade thickness affect performance of Archimedes spiral wind turbine (aswt)?

Recently, many wind turbines have been used to extract power from wind, such as Archimedes Spiral Wind Turbine (ASWT). In the current work, experimental and numerical studies are performed to elucidate the effect of the blades' thickness and the blade angles on the performance of ASWT.

What is a spiral wind turbine rotor?

This turbine is characterized by its simple design, ease of manufacture, and can be used in the generation of electric power in remote areas and new urban communities. The investigation of the two Archimedes Spiral Wind Turbine rotor designs was conducted numerically and experimentally.

How does a spiral wind turbine work?

For these turbines, the torque generated by the drag on the blade enables the rotor to rotate about an axis parallel to the ground. The Archimedes spiral wind turbine, a horizontal-axis drag-type turbine, is known to have slightly higher aerodynamic efficiency than those of vertical-axis drag-type wind turbines.

Which wind turbine blade has the highest efficiency?

The highest efficiency measured in their study was 12%. Lu et al. recently developed a design method for the Archimedes spiral wind turbine blade and performed a numerical simulation using ANSYS CFX.

What are the shape parameters of Archimedes spiral wind turbine blade?

Schematic diagram of the Archimedes spiral wind turbine blade: (a) Side-view of the Archimedes spiral wind turbine blade; (b) Geometry of a 0.5 kW Archimedes wind turbine blade. The shape parameters can be defined for the equation development. The shape parameters include γ, R 1, and S 1, as shown in Figure 2.
