6 FAQs about [H-type vertical axis wind turbine blade design]

Can vertical axis wind turbine airfoils increase wind power efficiency?

The current H-type vertical axis wind turbine (VAWT) airfoils are from horizontal axis wind turbine airfoils or symmetry airfoils that are designed at one angle of attack (such as α = 6°) rather than different angles of attack. As a consequence, it cannot, to a certain extent, increase wind power efficiency.

How to design a vertical-axis wind turbine with straight blades?

Designing a vertical-axis wind turbine with straight blades requires plotting power coefficient c p against tip speed ratio λ, as a function of rotor solidity σ (Fig. 1). Power coefficient for a VAWT, straight blades and symmetric airfoil

How is a vertical axis wind turbine (VAWT) H-Darrieus designed?

Numerical simulation is used to predict the performance of a Vertical Axis Wind Turbine (VAWT) H-Darrieus. The rotor consists of three straight blades with shape of aerofoil of the NACA family attached to a rotating vertical shaft. The influence of the solidity is tested to get design tendencies.
