“…The first known practical windmills were built in Sistan in the seventh century and were the first vertical axis windmills. However, it was not until the Cold War and the energetic crisis of 1970 that wind turbines were presented as a competitive source for electrical power generation (Subsecretaría de Energía Eléctrica, 2019; Yusof & Mohamed, 2020).…”

“…The Savonius turbine is a drag device and tends to produce a high starter pair; therefore, it reduces shear velocity and requires a low-velocity wind to start rotating; in addition, it has a lower efficiency than other turbines. It should be noted that conventional Savonius turbines are not suited for electrical power generation due to their inability to rotate faster than the wind (Hau, 2005;Yusof & Mohamed, 2020). Article In 1925, French engineer Georges Jean Marie Darrieus invented the Darrieus turbine; this turbine had curved blades that were positioned around a rotating vertical axis.…”

“…Wind turbines can be classified by the orientation of their rotational axes as horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT). A vertical axis wind turbine is a wind machine whose rotational axis is perpendicular to the wind's direction (Presses Internationales Polytechnique, 2002;Yusof & Mohamed, 2020).…”

“…Vertical axis wind turbines have several advantages when compared to horizontal axis wind turbines, such as: they are better suited for turbulent winds, changing wind directions, and low-velocity winds. In addition, they have no need of an orientation system, are less noisy, and have a simpler and more compact design (Presses Internationales Polytechnique, 2002;Yusof & Mohamed, 2020).…”

“…Vertical axis wind turbines have efficiencies of between 40-50%; this percentage is below the theoretical efficiency of a wind turbine. Therefore, there exists additional potential in bettering this type of turbine so as to increase its efficiency (Yusof & Mohamed, 2020). To better utilize the wind resource in wind turbines, devices called wind concentrators are used.…”

This work shows the computational simulation of the fluid dynamics of inductor discs (patent pending reception number MX/E/2021/002395) applied to vertical axis wind turbines (VAWT). These inductor discs have a unique and innovative design that can be classified as wind concentrators. The purpose of these devices is to increase wind velocity at the wind turbine entrance; this increase in velocity exponentially boosts the mechanical power of the turbine, according to Betz's theory, increasing the electrical energy production of the turbine and, at the same time, reducing its dimensions. The objective of this investigation is to carry out the fluid dynamic simulation (CFD) of two of the inductor disc geometries: an elliptical one and a truncated conical one, varying the entrance wind velocities of the VAWT from 3 m/s to 12 m/s. The proposed methodology consists of employing a CFD software (ANSYS) to model the two inductor disc geometries and extract them from a static control volume. Mesh this volume, establish boundary conditions, and vary wind velocities to carry out the fluid dynamic analysis. Finally, the obtained velocities are compared at different representative points of both geometries.
