A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set vertically. Unlike horizontal-axis wind turbines (HAWTs), VAWTs can operate regardless of wind direction. This makes them suitable for urban environments where wind direction is constantly changing.

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.

Windmills in Iran were designed to convert wind energy into mechanical energy through moving a wind wheel, which in turn activated a system of vertical rotation (axis) through a system of gears that in turn rotating the millstones to grind cereals and raise water from wells.
So vertical axis wind turbine needs an automatic brake system. As a wind turbine starts to brake, it must overcome the rotational inertia and the driving force from the wind. So a good design calculates the torque in the rotor at survival wind speed and chooses a suitable disk brake for that amount of energy. 2. Medium & large VAWT …
The power output of the wind turbine is given by Equation 1: P = 1 2 ρAv 3 ηTηG (1) Where: P=Power output (W) A=Sweep area (m2) ρ =Air density (Kg/m3) v=Wind velocity (m/s) η T=Wind turbine efficiency η G=Generator efficiency The equation shows the velocity cubed (v3), the rotor sweep area, the air density and the turbine and …
Cons of Vertical Axis Wind Turbines: Lower Efficiency: VAWTs often suffer from lower efficiency rates compared to HAWTs, mainly due to aerodynamic limitations and increased drag on the blades. Limited Scalability: Scaling up VAWTs can be challenging as the structural integrity of the turbine becomes more difficult to maintain with larger sizes.

Small domestic turbines would cost between $3000 -$8000 per kilowatt of generated ...
decide on the style of our windmill. We decided to build a vertical-axis windmill because horizontal-axis windmills face only one direction and thereby receive wind from one direction, whereas vertical-axis windmills can receive wind from any direction. This makes the vertical-axis windmill more cost effective than the horizontal-axis windmill.

1. Lower Noise Levels. One of the key advantages of vertical axis wind turbines is their reduced noise output compared to horizontal axis wind turbines (HAWTs). HAWTs can produce significant noise due to the high-speed rotation of their blades. In contrast, VAWTs operate at lower rotational speeds, resulting in quieter operation.
