摘　　要：建立了外循环双层玻璃幕墙二维稳态物理模型,采用Fluent软件模拟分析了内置遮阳百叶对双层玻璃幕墙热工性能的影响,结合幕墙空腔内的速度分布规律,对不同工况下的幕墙传热及通风特性进行了对比,得到了优化的百叶开启角度、百叶宽度和百叶间距等参数。The two-dimensional CFD model of double skin fa c, ade in steady state is established. Influence factors of inner shading louver on thermal performance of external respiration double skin fac, ade are analyzed through Fluent software. A comparative analysis on heat transfer and ventilation characteristics of curtain wall is conducted under different working conditions which combine with velocity distributions inside heat passage of glass curtain wall. Finally, optimized simulation results are obtained under structural parameters as follows：blind angle, spacing of blinds and width of blinds.
