摘　　要：基于内置遮阳百叶的外循环双层通风幕墙三维物理模型,利用WINDOW软件计算出内外幕墙的材料属性,然后采用FLUENT软件,使用太阳加载模型模拟双层通风幕墙热通道内的温度场和速度场,得到热通道内的温度和流动特性,并且计算出热通道的动态隔热效率。研究表明,热通道内的速度场和温度场以耦合的方式影响双层通风幕墙的热工性能。Based on 3D physical models of the external double skin facade （DSF） with built-in shading shutters, the material properties of the interior and exterior skin facades can be worked out by using WINDOW software. The simulation of solar loading model of the temperature field and velocity field, which can be found in the hot channel of double skin facades, can be achieved by using FLUENT software, thus obtaining the temperature and flow properties and the dynamic insulation efficiency of the hot channel. The study shows that the temperature and velocity distribution in hot channels, both working in a coupled manner, affect the the insulation performance of double skin facades.
