Resumen

Considerando que cada vez más turbinas eólicas operan en condiciones de turbulencia, este estudio sobre la intensidad de turbulencia (TI) en distintas áreas transversales en un túnel de viento se llevó a cabo. Un túnel de viento con un área de pruebas de 15 m de largo, 3.6 m de ancho y 2 m de alto se utilizó; se colocó una cuadricula de madera para generar turbulencia en el flujo y la velocidad del ciento se midió con un anemómetro de hilo caliente. Para determinar si hubo variaciones en la TI se definieron cinco puntos (centro, arriba, abajo, izquierda y derecha) en cuatro áreas transversales luego de la cuadricula de madera. Se determinó que la TI varía drásticamente dentro del área. Se calculó un porcentaje de error desde 3.6 % a 15.2 % cuando se consideraba la variación de la turbulencia dentro del área del rotor en comparación con cuando se usa solamente el punto en el eje del rotor. Para poder describir apropiadamente el flujo turbulento es necesario considerar el promedio de las mediciones de la turbulencia alrededor del área que cubre el rotor.
