摘　　要：本文采用CFD模拟的方法,对4种不同玻璃组合方式的双层幕墙的通风和传热性能进行了研究。其中一组CFD模拟结果与相关文献的试验数据进行了比较,结果吻合良好。研究表明:不同的玻璃组合方式对玻璃表面温度有很大影响,但对空腔气温则影响不大;不同的玻璃组合方式对风速的影响表现为靠内侧空腔较为明显,靠外侧空腔影响不大。Through CFD simulation, the performance of ventilation and heat transfer of double curtain wall with four different glass curtain organization patterns is studied. One of the simulation results coincides well with the experimental data in a relevant document. The study shows that glass curtain organization pattern has great influence on the temperature of glass curtain surface, but has little influence on the temperature of air in the cavity. At the same time, the glass curtain organization pattern has obvious influence on the wind speed of the inner cavity but little influence on the outer cavity.
