摘要
通过一个含有内热源面的三维房间模型,运用FLUENT软件对相同条件下,不同的辐射模型进行了数值模拟计算。通过计算结果的比较分析得出:对于这样一个具有热表面的封闭空间的对流、辐射换热问题,采用DO辐射模型与k-ε模型的耦合计算能够得到较好的计算结果。
In this paper, through a heat source containing the three-dimensional room model, the use of FLUENT software on the same conditions, different radiation models are calculated by numerical simulation. Through the comparative analysis of calculation results obtained： for a closed space with surface heat convection, radiation heat transfer calculation problem, can get better results by DO radiation coupling model and k-εmodel.
