【摘要】 为了研究住宅中间凹口位置对室内自然通风效果的影响,本文通过对近5年武汉市住宅小区形式的统计分析,建立3种常见的凹口位置布局的四户型高层住宅模型,并使用开源的计算流体力学软件OpenFOAM对这3种模型进行风环境模拟分析。结果表明,在凹口面积达到一定的条件下,凹口的设置对中间单侧通风户型室内自然通风效果有显著影响,但并不总是促进作用。在建筑平面中心设置凹口,更有利于中间单侧通风户型的自然通风效果。而凹口位于双侧通风户型与单侧通风户型之间时,中间楼层的单侧通风户型自然通风作用将减弱。更多还原

【Abstract】 In order to study the influence of the notch position of high-rise residential buildings on indoor natural ventilation, three ideal models with the layout of the recesses based on the statistical analysis of the residential quarters in Wuhan in the past 5 years were established. The computational fluid dynamics software OpenFOAM was employed for the wind environment simulation analysis. The results show that the application of the notch has a significant impact on the indoor natural ventilation of the single-sided room in the middle of the buildings, but which is not always promotive. The notch in the center of the building is more conducive to the natural ventilation of the single-sided ventilation room. When the notch is located between the double-sided and the single-sided ventilation room, the natural ventilation effect of the single-sided ventilation room will be weakened, especially for those near the mid-layer of the buildings.更多还原
