Abstract

This study evaluates the behavior of the wind from its speed in representative urban canyons of residential buildings in the city of Quito. The methodology was based on the selection of case studies from the area of Concepción located in the north of the city to build simplified models according to their aspect ratio height / width (H / W) in blocks of 250 m by 250 m. In each case includes multiple configurations of urban canyons, giving priority to the west-east and north-south orientations, which are simulated by the application of Computational Fluid Dynamics (CFD). The local wind is evaluated according to pedestrian height and their predominant direction obtained from the historical information obtained from the weather station in the area. The results show that the predominant relationship of the wind retains higher speeds when it flows canyons with a lower H/W ratio.
