A numerical study of three-dimensional wind flow around a tall building is presented in this paper. The solution is obtained by solving weakly compressible flow equations, along with Smagorinsky's subgrid-scale turbulent model. The numerical scheme is based on MacCormack's predictor-corrector explicit finite volume method. First, the numerical model was verified by testing a shear flow around surface--mounted cube, then a detailed study was carried out for a shear flow around a taller building model (width:length:height = 1:0.889:4.667). The main task of this paper is to explore the large-scale vortex structure and the unsteady behavior of flow around a tall building, which are still not well understood.
