A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. The forces and the velocities acting in a Darrieus turbine are depicted in Figure 1. The resultant velocity vector, $${\displaystyle {\vec {W}}}$$, is the vectorial sum of the undisturbed upstream air velocity, VAWTs offer a number of advantages over traditional (HAWTs):• Omni-directional VAWTs may not need to track the wind. When the speed of a VAWT wind turbine grows, so does the power; however, at a certain peak point, the power progressively decreases to zero even while the wind turbine speed is at its greatest. The Darrieus rotor comes in various subforms, including helix-shaped, disc-like, and the H-rotor with straight blades. A 2021 study simulated a VAWT configuration that allowed VAWTs to beat a comparable HAWT installation by 15%. An 11,500-hour simulation demonstrated the increased efficiency, in part by using a grid formation.
