The waste of the wind resource in emerging countries is not only due to the lack of implementation of large-scale wind farms of, but because, in the most of territories the average wind speeds do not reach to the minimum magnitude (3 at 4 m / s) of starting of the commercial wind turbines, which means that this resource is not used. Therefore, in this article we describe the design and characterization of a mechanical element (wind concentrator) that allows increasing the wind power available in a low powerwind turbine. The study is broken down into three stages: in the first stage an experimental analysis is conducted in order to validate and to identify the profile of surrounding velocities in the concentrator. Inthe second stage, a modeling is carried out throw the 5th order equation of Bell & Mehta, by implementing Matlab and exporting the data to Solid Edge. In addition, the phenomenon is described by the equation of conservation of mass and conservation of energy. In the third stage the simulation is carried out by meansof finite elements supported by the software ANSYS, whose objective is to determine the relation of theoptimal area of entrance and exit of the concentrator. Finally, it is concluded that the concentrator allows the increasing of the wind potential of the order 2.37 times.

El desaprovechamiento del recurso eólico en los países emergentes no es solo por la falta de la implementación de parques de aerogeneradores de gran escala, sino porque, en la mayoría de los territorios las velocidades promedio del viento no alcanzan a contar con la magnitud mínima (3 a 4 m/s) de arranque de los aerogeneradores comerciales, lo cual hace que este recurso no sea aprovechado. Por lo anterior, en el presente artículo se describe el diseño y caracterización de un elemento mecánico (concentrador eólico) que permite aumentar la potencia eólica disponible en un aerogenerador de baja potencia. El estudio estáfraccionado en tres etapas: en la primera etapa se realiza un análisis experimental con el fin de validar e identificar el perfil de velocidades circundantes en el concentrador. En la segunda etapa se realiza unmodelado mediante la ecuación de 5to. orden de Bell & Mehta, implementando Matlab y exportando los datos a Solid Edge. Además, se describe el fenómeno mediante la ecuación de conservación de masa yconservación de energía. En la tercera etapa se realiza la simulación mediante elementos finitos soportadopor el software ANSYS, la cual tiene como objetivo determinar la relación de área óptima de entrada ysalida del concentrador. Finalmente, se concluye que el concentrador tiene un aporte significativo en elaumento del potencial eólico disponible del orden 2.37 veces.
