There are different turbulent models that have significant impacts on aerodynamic
performance and simulation of wind flow over urban areas. A built-up urban area that
contains a set of mid- to high-rise buildings was used to highlight theimpact of
different turbulence models such asRe-Normalization Group(RNG)k-epsilon, Shear-
Stress-Transport (SST)k-omega on the aerodynamic performance of wind flowingin
different directions.For both approaches, simulation results such as pressure, mean
velocity, and kinetic energy at different directions were obtained and compared. The
results demonstrate that, givenan acceptable iterative time andthe same boundary
conditions and input variables, both modeling approachesproduce similar resultsfor
pressure and velocity around the urban area and slightly different results for the
kinetic energy at some location in the urban region, as well as along the height of the
buildings considered herein.
