Abstract. Most wind farms consist of horizontal axis wind turbines (HAWTs) due to the high power coefficient (mechanical power output divided by the power of the free-stream air through the turbine cross-sectional area) of an isolated turbine. However when in close proximity to neighboring turbines, HAWTs suffer from a reduced power coefficient.

Vertical axis turbines are easily distinguishable because of their vertical shape. Unlike the horizontal axis turbines, vertical ones come with a variety of shapes and designs. This article will tell you about vertical axis turbine, its types, and why it can be an alternative to horizontal ones. Vertical Axis Wind Turbine (VAWT)

A vertical axis sail-type wind turbine includes an array of sail-like structures that are mounted on rotating main masts. The sail-like structures can be oriented to interact with the wind. For example, when the sail-like structures are moving in a downwind direction, they are oriented to present a flat surface that is perpendicular to the wind direction.
