Vertical Axis Wind Turbines (VAWTs) are a type of wind turbine that is characterized by having a vertical axis of rotation. These wind turbines represent a a promising al- ternative to fossil fuels for the production of energy that is sustainable. For this reason, they have been the subject of many research studies in order to define their performance and improve their design. However, their unique configuration presents some aerodynamic challenges that require innovative solutions. In fact, the vertical-axis configuration involves unique aerodynamic field complications such as the generation of swirling wake and the interaction of the blades with it. Vortices can cause large fluctuations in the velocity and in the direction of flow at the turbine blades, negatively affecting the overall performance of the turbine, resulting in increased drag aerodynamics and a reduction in the lift force generated by the blades.
