屋顶植被层传热的数值模拟研究

Numerical Simulation on Heat Transfer of Roof Vegetation

分析了当前对屋顶种植层的研究现状以及对屋顶植被层进行理论和实验研究的意义;在前人的研究成果的基础上,对自然植被层进行理论与试验研究,找出自然植被层所表现出的热特性。结果表明:自然植被传热的理论模型与试验测试较为吻合,能够很好地说明本植被层的温度变化规律,为进一步研究其他植被层的热特性提供了有益的参考。

The current situation about planting roof and its theoretical and experimental significance were analysed.Based on previous research results,the authors carried out theoretical and experimental studies on natural layer of vegetation to find out its thermal property.The experiment showed that theoretical model of natural vegetation heat was more consistent with the experimental test,and would provide a useful reference for further studies on other layer of vegetation＇s thermal property.
