摘　　要：采用现场测试和计算流体力学(CFD)分步模拟法相结合的方法研究了丘陵地形和建筑形式与构造对湖南北部地区的某传统民居的自然通风效果的影响.根据现场测绘建筑形式和丘陵地形的数据对研究对象进行简化,以测试的冬、夏气象参数、夏季壁面温度、冬季采暖热源作为边界条件,模拟结果表明,地形特征及建筑总平面布局、建筑形式和建筑构造对建筑自然通风影响较大,且模拟结果与建筑内外的11个测点的风速测试结果比较吻合.因此,丘陵地区的复杂边界条件下,CFD分步模拟法可用于居住建筑的模拟设计,以改善其夏季自然通风并减少冬季冷风渗透.Combined with the research of field testing and the step-by-step CFD simulation method, the effects of hilly topographical features and building forms and construction of traditional houses, located in the north of Hunan Province, on natural ventilation in winter and summer were studied. The model of the study was simplified on the basis of the data of mapping on the target traditional house and hilly hypsography. Furthermore, the data of meteorological parameters in winter and summer, the wall temperature in summer and the heat source of heating in winter, which were obtained by the testing, were regarded as the boundary conditions of the model. Simulation results showed that the hilly topographical features and the general plan, forms and construction of the target traditional folk house had great effects on the natural ventilation. Meanwhile, the results agreed with the testing results of wind velocity from eleven points which were placed inside and outside of the building. Therefore, the proposed two-step simulation method can be used in the natural ventilation design of residence buildings, which have complex boundary conditions in hilly area, in order to improve the natural ventilation in summer and reduce the infiltration in winter.
