摘　　要：为了研究高层住宅外窗设计样式对室内自然通风效果的影响,文章通过总结高层住宅起居室和主卧室外窗常见设计样式,使用CFD软件Fluent对建筑外窗常见的典型设计样式的室内流场进行模拟分析。模拟结果表明,在外窗尺寸和开启扇面积相同的情况下,外窗开启扇相对位置对室内流场分布影响很大;在外窗尺寸相同的情况下,窗户分格数和开启扇数量增大,室内平均风速和R值增大,但其存在临界值,超过临界值,R值明显减小。文章依据模拟结果,并结合相关标准规范,对高层住宅外窗设计提出优化建议。In order to study the influence of the window design of high-rise residential buildings on the indoor natural ventilation, this paper summarizes the common window design styles of the living room and master bedroom in high-rise residential buildings in Xi’an, and uses CFD software Fluent to simulate the indoor flow field of the typical window design style of the buildings. The simulation results show that when the window size and the opening fan area are the same, the relative position of the window opening fan has a great influence on the indoor flow field distribution. Besides, in the case of the same window size, if the number of windows and the number of opening fans increases, the indoor average wind speed and R value also increase, but there is a critical value. When the critical value is exceeded, the R value is significantly reduced. Finally, based on the simulation results and the relevant standard specifications, the optimization suggestions for the window design of high-rise residential buildings is proposed.
