摘要
应用基于CFD的数值风洞技术对某幕墙建筑房间单元的通风特性进行了分析,气流的计算采用标准k-ε湍流模型,模拟结果表明,在幕墙的凹面侧边开窗比在幕墙正面开窗具有更佳的通风效果。
CFD-based numerical wind tunnel techniques were used to analyze the ventilation features of a room cell in a facade building. Standard k-ε turbulence model was chosen to calculate the air flow. The simulation showed that better ventilation performance can be achieved when openings were installed in the front side of the facades other than in the concave side.
