“…Exposure category C with a power law exponent of 0.22, which represented an urban terrain with dense buildings, was simulated according to the Chinese Load Code (GB50009-2012, 2012). For details of the wind tunnel and terrain conditions, please refer to the literature (Peng et al, 2020). The mean wind speed and the turbulence intensity at the roof height of the model were 10 m/s and 11.3%, respectively.…”

The interference effects between two tall buildings on building surface wind pressures are studied by using wind tunnel experiments. Different breadth ratios ( B r = B interfering/ Bprincipal), depth ratios ( D r = D interfering/ Dprincipal), and relative locations of the two buildings are tested. The results show that the interference effects on mean wind pressures on the windward face and the right face are more considerable than those on the other two faces. The windward face mainly shows the shielding effect, while the right face exhibits the amplification effect. The surface interference factors ( SIF) of windward and right faces under different breadth ratios and depth ratios have clear correlation with the reference values ( B r = D r = 1.0), and a series of correlation formulas are obtained. The SIF values of the windward face in tandem arrangement and the maximum and minimum interference factors of the right face in parallel arrangement are formulated. The most prominent local peak pressure under different cases mainly concentrates in the side edge and upper edge of the windward face, the left upper corner, left lower corner, and the upper-middle part of the right face.

“…Como se indica en el cuadro 1, este túnel posee dos secciones de prueba y en una de ellas, el túnel se combina con un canal de olas (ver figura 7), por lo que se han realizado investigaciones diversas respecto a recurso eólico y su relación con el recurso marítimo. En [63] se estudian las características de los flujos de aire sobre edificios altos con techo plano, concluyéndose que entre mayor es la razón de altura-profundidad y ancho-profundidad del edificio, mayor es el factor de amplificación de la energía del flujo. También, en [64] se analizó por medio de sensores de posición, acelerómetros y válvulas extensiométricas, el rendimiento estructural de una turbina eólica empotrada en arena.…”

Se presenta una revisión de literatura de los túneles de viento con mayor relevancia en la investigación sobre energía eólica. Se realizó una búsqueda sistemática en la base de datos de Web of Science (WoS) en la que se obtuvieron 93 artículos que fueron filtrados para el periodo 2016-2020 y mediante distintos criterios de relevancia. Los artículos permitieron identificar 34 túneles alrededor del mundo. Se seleccionaron los ocho túneles de viento con mayor volumen de publicación y se presentan los estudios realizados en estos. Los principales temas encontrados en la revisión tratan sobre turbinas de eje horizontal y vertical, estelas, perfiles aerodinámicos y recurso eólico. Esta revisión tiene como objetivo servir de referencia para los investigadores en energía eólica que requieren realizar experimentos en túneles de viento.
