摘要
磷石膏空腔结构对楼盖保温性能有较好的提升。目前对其保温性能的研究主要是传统的二维导热模型,其误差不可忽视。根据辐射传热的离散坐标法,借助Fluent软件对单个磷石膏空腔体进行辐射传热分析,分别得到了考虑磷石膏壁传热与不考虑其传热的两种情况下的空腔内辐射强度场以及空腔内温度场。
Phosphogypsum cavity slab has good heat preservation performance. Nowadays,the researches on heat preservation performance of phosphogypsum cavity slab are mainly based on the two-dimensional heat transfer model, the error of which can not be ignored. In this paper,we used the discrete ordinate method to analyze the radiation heat transfer in the phosphogypsum cavity slab,and obtained the radiation intensity field and temperature field of the cavity slab under the two conditions: considering the heat transfer of phosphogypsum walls or not.
