摘　　要：以西安某住宅小区为研究对象,根据实际楼盘几何尺寸建立二维物理数学模型,采用CFD计算方法,得到冬夏季室外速度场及压力场分布,并以此计算结果作为三维室内自然通风气流计算的边界条件对室内进行模拟,最终确定具有自平衡新风口的住宅室内的速度场分布,依此进行自然通风方案的优化。The object of this research is a residential district in Xi＇an.The outdoor wind environment of the residence in summer and winter is simulated by using 2D CFD method,which result is used as boundary condition in the 3D simulation of indoor wind environment.The velocity distribution of the residential district with self-balancing air vent is calculated,and the optimization method is propounded.
