摘　　要：利用CFD模拟技术软件,按绿色建筑评价要求,对中国移动南方基地2.1栋室内外风环境进行数值模拟。根据各季节主导风向和平均风速,模拟得出建筑周围的风速分布规律,为室内自然通风环境提供了良好的条件;继而利用CFD模拟技术研究太阳辐射诱导热压通风条件下的自然通风状况;针对内设中庭、外设玻璃幕墙的建筑结构,对不同的开口设计方案进行比较分析,以换气次数、风速、气流组织均匀性等参数为评价指标选取适用于本建筑的最优方案。With CFD simulation software, both the indoor and outdoor wind environment of “South Base building 2. 1” of China Mobile are numerically simulated in accordance with the requirements for green building assessment. According to the dominant wind direction and awerage wind speed of each sea-son, the simulation result obtained wind speed distribution around th, e building, which provide a good con-dition for indoor natural ventilation environment. The CFD simultion technology is utilized to study the natural ventilation under the thermal pressure ventilation induced by solar radiation. Various openings de-sign schemes are compared and analyzed for the building structure with atrium and glass curtain wall. The indicators including ventilation rate, wind speed and air distribution uniformity as evaluation index are used to select the optimal scheme for this construction.
