Vertical-axis wind turbines do not need to be oriented to the wind direction and offer direct
rotary output to a ground-level load, making them particularly suitable for water pumping …

This paper reviews the initial development of the design and operation of modern vertical
and horizontal axis wind turbines, with the aim of comparing the development of the two …

Darrieus-type straight-bladed vertical axis wind turbines (SB-VAWTs) are more appropriate
for generating electricity than other VAWTs mostly suitable for regions having low to medium …

Vertical axis wind turbines (VAWT) may offer operational and design advantages over their
horizontal axis counterparts, but the occurrence of dynamic stall and the resulting cyclical …

In recent decades, the high fatigue loads (mainly derived from the blade normal force
fluctuation) and low power coefficient at the low tip speed ratio with high incoming wind …

The desirable performance attributes of a vertical axis wind turbine (VAWT) include high
starting torque, high peak efficiency, broad operating range and a reasonable insensitivity to …

Floating vertical axis wind turbines are bearing complex aerodynamic fatigue loads due to
the movement of the platform and the reciprocating variations in the angle of attack and the …

In recent years the Darrieus wind turbine concept has been adapted for use in water, either
as a hydrokinetic turbine converting the kinetic energy of a moving fluid in open flow like an …

This paper describes the performance of a micro vertical-axis wind turbine with variable-
pitch straight blades. The proposed variable-pitch angle mechanism has an eccentric point …

Darrieus type hydrokinetic turbines (HKTs) with fixed pitch blades, like their wind turbine
equivalents, exhibit poor starting torque whether blades are straight, troposkein or helical …
