摘　　要：基于格子BGK方程的三维15点格子Boltz-mann模型,对建筑物周围流场进行了数值仿真,对其流场的划分进行了分析,并对不同雷诺数下建筑物周围的流场进行了数值模拟计算,得到了比较满意的结果,为环境质量的评估提供了新的途径.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.
