| 摘 要： | 利用计算流体动力学模拟了传统民居当大门建筑群丘陵地形下选址与自然通风的关系.该模拟包括不同气候与地形下的4个案例及其建筑周边风压与风速分布.模拟结果显示:山体能够降低建筑迎风面和背风面的风压绝对值;在有山体的地形中天井对自然通风的促进效果大于没有山体的地形,对比冬季与夏季天井效果时也可得到同样结论;作为障碍物,山体还能降低建筑周边的风速,且由于冬夏季风向不同,山体的影响程度呈现出较大区别.分析结果表明,丘陵位于建筑北向的选址方式可以解决亚热带气候条件下住宅冬夏2季不同的自然通风需求而造成的矛盾,尤其在含天井的住宅中最为显著.

| Abstract: | The relationship between the site selection of a hilly terrain and the natural ventilation of the Dangdamen building complex,which is a traditional folk house,is revealed by a computational fluid dynamics（CFD）simulation.The wind press and speed distributions around the building in four cases with different weather conditions and topographies are simulated.The simulation results show that a hill can reduce the absolute values of the wind pressure at the windward and leeward sides of the building.The encouraging effect of the patio on the natural ventilation in a terrain with a hill is greater than that without a hill.The same situation occurs when comparing the patio effects between summer and winter.The wind speed around the building can be reduced by the hill as it is an obstacle and the degrees of the influence of the hill in summer and in winter are quite different because of different wind directions.The analysis results show that this kind of site selection,with the hill to the north,is a suitable way to settle the conflict of the natural ventilation requirements in summer and in winter under subtropical climate conditions,especially in houses with patios. |
