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。
In this paper, the CFD simulation method for the four different combinations of glass curtain wall ventilation and heat transfer performance were studied. One set of CFD simulation results with the experimental data of the relevant literature were compared, the results agree well. The results show that different combinations of glass have a great influence on the temperature of the glass surface, but have little effect on the temperature of the glass. The effect of different glass combinations on the wind speed is more obvious on the inner cavity and on the outer cavity Not big.
