Abstract

Numerical simulation of airflow in the vicinity of several rectangular-shaped buildings and airflow and dispersion around an L-shaped building S. Tehranian, S.R. Hanna & R. Lohner Institute for Computational Sciences and Informatics, George Mason University, USA 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
