Resumen (es)

Contexto: Las turbinas eólicas de eje vertical y en particular las turbinas de arrastre tipo Savonius aventajan a los otros tipos de turbinas en aplicaciones que comprenden vientos erráticos y de baja velocidad. Si bien su eficiencia está entre las más bajas, esto puede verse compensado con los bajos costos que llegan a representar, convirtiéndolas en una alternativa sostenible que toma interés en este tipo de aplicaciones. En esta investigación se busca seleccionar la geometría para el alabe de una turbina eólica tipo Savonius que presente el mayor rendimiento.

Método: Para ello, se analizan numéricamente diversas configuraciones geométricas consultadas en la literatura, empleadas en este tipo de turbinas. Todos los modelos de perfil son estudiados bajo los mismos parámetros y modelos de la dinámica de fluidos computacional a través del software ANSYS Fluent.

Resultados: A través de las simulaciones computacionales se estiman las condiciones de optimo rendimiento de cada una de las geometrías. Dichas condiciones permiten comparar bajo los mismos términos el desempeño de los perfiles, e identificar los de mayor rendimiento. Se determina que el perfil semicircular convencional y el conocido como Bach modificado presentan un coeficiente de potencia de 0,287 y 0,395 respectivamente, lo que representa un aumento en su rendimiento del 37,8 %.

Conclusiones: Este resultado superior motiva a un análisis en detalle del perfil Bach modificado que permita encontrar las proporciones geométricas óptimas para su desempeño aerodinámico.

Resumen (en)

Context: Vertical axis wind turbines, and in particular Savonius type turbines, outstrips the other types of turbines in applications that include erratic and low speed winds. Although its efficiency is among the lowest, this can be compensated by the low costs that come to represent, turning them into a sustainable alternative that takes interest in this type of applications. This research seeks to select the geometry for the blade of a Savonius type wind turbine that presents the highest performance.

Method: For this, various geometric configurations consulted in the literature, used in this type of turbines, are numerically analyzed. All the profile models are studied under the same parameters and models of the computational fluid dynamics through the ANSYS Fluent software.

Results: Through computational simulations, the optimal performance conditions of each of the geometries are estimated. These conditions allow the performance of the profiles to be compared under the same terms, and to identify the ones with the highest performance. It is determined that the conventional semicircular profile and the one known as modified Bach have a power coefficient of 0,287 and 0,395 respectively, which represents an increase in performance of 37,8 %.

Conclusions: This opens the door to a detailed analysis that allows the optimization of the aerodynamic performance of this profile.
