【摘要】 本文利用计算流体力学(CFD)软件,针对串行排列的三栋建筑物的风环境,采用标准k-ε两方程湍流模型进行了数值模拟,研究分析了三种不同建筑物间的距离下的风涡漩分布特点,并定量分析了涡漩区中的风速和湍流强度,以及建筑物横截面的压力系数分布,为建筑小区的规划最优设计提供理论参考和依据。更多还原

【Abstract】 Numerical calculations of wind turbulent flow around three serial buildings are performed by the standard k-ε model.The vortex distribution of the buildings in cases with three different distance in between is analyzed detailedly.The wind speed and the turbulent intensity in the vortical flow area and the pressure distribution on the buildings are analyzed quantitatively.The results can offer as a foundation for optimizing the plan and the design of residential area.更多还原
