| Abstract: | A three-dimensional 15-bit LB modelbased on lattice BGK equation is proposed to sim-ulate flow fields around buildings. The division ofthe flow field and the boundary treatment are an-alyzed. Good results of flow fields around build-ings are obtained under different Reynolds numbers, which may provide a new method for environmental evaluations. |
