Numerical and experimental investigation of wind flow in urban area

Hubova O., Macak M.
pages 317 - 320, full text

The analysis presented in this paper is a preliminary modeling of the wind flow at the site of the planned complex of high-rise buildings using FLUENT ANSYS program. The high-rise buildings in built-up area affect the surrounding pedestrian level and also wind comfort on the terraces and on corners and crossing passages. We indicated the high wind speed areas for discomfort under strong wind condition experimentally in the aerodynamic tunnel with boundary layer in Bratislava and using CFD simulation taking into account the existing and planned buildings configuration. We also solved the task on the selected object in a simplified way according to the valid EN 1991-1-4 and NA standards. Local suction extremes, which are slightly higher than the standard, appeared at wind directions that are common in the area, i.e. the north and west winds.
