This paper presents the modeling and simulation results of wind velocities in urban areas. The main idea was to build random generated urban areas for studying the influence of different urban geometries, from relative open to more dense, on wind profiles. The Spalert-Allmaras turbulent flow model turned out to be suitable for domains up to 50 x 50 x 100 m^3. The k-ε turbulence model provided reliable results for domains up to 100 x 600 x 2000 m^3. We conclude that the presented methodology is promising for 3D CFD modeling of urban areas for built environment applications.
