Vertical-Axis Wind Turbine Design. VAWTS feature a main rotor shaft which is positioned vertically. Thanks to this arrangement, the turbine does not have to face the wind for it to be effective. This comes as a plus on sites where the wind direction varies a lot – for instance when integrated into a building.

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.
