Vertical axis wind turbines (or VAWTs) have the main rotor shaft arranged vertically. Key advantages of this arrangement are that the turbine does not need to be pointed into the wind to be effective. This is an advantage on sites where the wind direction is highly variable. VAWTs can utilise winds from varying directions.

The wind pressure is the amount of force exerted by the wind per unit area of the blades and is given by: P = 1/2 (1 + c) * ρ * v 2. Where c is a constant and equals 1.0 for long flat plates. The force of the wind against the windmill blade is based on the wind pressure multiplied by the area of the blade facing the oncoming flow.

Efficiency – When the wind blows on the blades of a HAWT, all of them contribute to energy production. When wind blows on a vertical-axis turbine, only a fraction of the blades generate torque while the other parts merely 'go along for the ride'. The result is comparably reduced efficiency in power generation.

The lift-based Darrieus design looks like an eggbeater and uses long airfoil shaped blades (i.e. tapered like airplane wings) to extract energy as the wind strikes the blades perpendicularly. There are several variations on the Darrieus rotor, including some that have straight blades, which are often called Gyromills (e.g. the Windspire, Fig. 20.12) and more advanced designs …

Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that's why it got such a name.

The Gedser turbine (three blades, 24 m rotor, 200 kW, Figure 1 b) was the first success story of wind energy, running for 11 years without maintenance. In this way, the linkage between the success of wind energy generation technology and the application of composite materials became an issue from the beginning: the first turbine, built with steel blades, failed, …

Savonius Vertical-Axis Wind Turbine. The Savonius vertical-axis wind turbine uses cups, called scoops, instead of blades to capture wind power. Figure 5 shows an example of a Savonius vertical-axis wind turbine. When the wind blows, it creates a positive force in the scoop and a negative force on the back side of the scoop.

A vertical axis wind turbine with a turbine rotor with rotor blades disposed for rotation about a substantially vertical axis. The turbine includes multiple vertically extending stator vanes circumferentially spaced apart about the rotor in an annular array. Each vane has a radially inward facing surface, a radially outward facing surface and a flange on an outer edge of each vane.

A vertical axis wind turbine (VAWT) has blades mounted on the top of the main shaft structure, rather than in the front like an aircraft rotor. The generator is usually placed at the tower base. Used less often than their horizontal counterparts, VAWTs are more practical in residential areas.

The blades on a vertical wind turbine see a uniform airspeed along the length of the blade, as well as the same angle of attack, so they can be much simpler in terms of design. The blades on a Darrieus turbine can be simple aerofoils and don't have a need for complex additions to enhance the aerodynamics.

Vertical axis wind turbines are wind turbines whose rotors rotate around a vertical shaft with vertically oriented blades. They produce electricity by utilizing wind power the same way horizontal axis wind turbines do: Wind drives the rotor to turn, the rotation connects to the generator, and the generator converts the mechanical energy into electricity.

Vertical home wind turbines are designed with blades which point straight toward the sky, rather than outwards (though are just as aerodynamic as horizontal turbine blades) – this is to maximise the space available to the homeowner, who likely does not have the free available land necessary to install a standing horizontal turbine.
