对设有空中花园的建筑群内流场进行了数值模拟 ,分析了来流方向、建筑物间距、建筑物高度及空中花园体积等因素对建筑物自然通风的影响。模拟结果表明 ,在上游建筑物上设置空中花园可以改善下游建筑物的自然通风效果 ;在第 1排建筑物上设置空中花园和在前 2排建筑物上设置空中花园 ,对下游建筑物自然通风的影响没有明显区别 The numerical simulation of the flow field in a building with a sky garden is carried out. The influences of the flow direction, the distance between buildings, the height of a building and the volume of an air garden on the natural ventilation of a building are analyzed. The simulation results show that the provision of sky gardens on the upstream buildings can improve the natural ventilation effect of the downstream buildings; the provision of sky gardens on the first row of buildings and sky gardens on the first two rows of buildings and the natural ventilation of the downstream buildings The impact of no significant difference
