摘要:
为研究夏热冬暖地区高密度城市中建筑外立面构件(遮阳板、翼墙和阳台等)对建筑室内外气流组织与室内自然通风的影响,采用计算流体力学数值模拟,通过改变来流风向、上游扰流建筑的高宽比以及垂直与水平外立面构件,建立了18个不同案例,模拟了不同位置房间室内自然通风换气次数效果. 结果显示,当来流风向与建筑外窗法线方向成角度时,目标建筑所有房间均增加了换气次数. 同时,外立面构件对室内自然通风效果的影响高度依赖于环境因素,包括近地面风向、目标建筑方位朝向和上游扰流建筑的高度比值,这些参数的相互作用影响了流场特性,并改变了立面构件对目标建筑自然通风效率的影响效果. 本研究提升了室内自然通风效率与空气品质,可为建筑立面优化设计提供借鉴.
Abstract:
For wind-induced natural ventilation, a surrounding building and buildings’ envelopes are two main factors to affect the indoor air flow characteristics. There are few research works studying the effect of surrounding buildings on indoor natural ventilation. In this work, Computational Fluid Dynamics (CFD) method was employed to model 18 different cases to investigate numerically the effect of an upstream building with two different heights to the target building with two different types of wing walls under two different wind directions (wind incidence angle α=0° and α=45°). The results show the target building generally has a better natural ventilation performance when the wind obliquely incidents on the building. In addition, the effect on ventilation performance of wing walls is highly dependent on the environment including the approaching wind directions, the orientation of the target building and height of the upstream building.
