Abstract

A computational model has been developed to determine wind characteristics in the wake of a rectangular building and validated against previous field-test results. Dimensions of the recirculation zone behind the building have been determined using the Reynolds-Averaged-Navier-Stokes (RANS) equations for two different wind incidence angles, i.e. for wind normal to the longer building side and for wind normal to the shorter building side. Obtained results show a decrease in the recirculation zone length for rougher terrains. Therefore, numerical results presented in this paper proved to be in good agreement with full-scale results indicating that the approach taken in this study can be successfully applied in calculating dimensions of recirculation zone in the wake of a rectangular building for various terrain types.
