Abstract
A three-dimensional numerical code, FEFLO, which is based on finite element
techniques with unstructured tetrahedral grids, has been used to simulate the
airflow in the vicinity of several rectangular-shaped buildings. A set of
experimental data taken at the EPA Meteorological Wind Tunnel was used to
evaluate the numerical code for atmospheric urban airflow modeling. The flow
obstacles consisted of various rectangular-shaped blocks immersed in a
simulated neutral atmospheric boundary layer. The equations solved were the
Reynolds-averaged Navier-Stokes equations with the standard k-£ model as the
turbulence model. The FEFLO-simulated airflow showed good agreement with
observed airflow patterns, including sizes
