Theory and Numerical Simulation of 3D Discrete Transfer Radiation Model

本文比较详细地阐述了三维离散传播热辐射模型的理论，并且编制了相应的数值模拟程序；运用该程序对三维立方腔体中的两种辐射传热问题进行了数值模拟，所得模拟结果与精确解吻合较好，这表明三维离散传播热辐射模型是目前解决辐射问题中热流量和温度分布的一种较好的方法。

he theory of 3-dimensional discrete transfer radiation model is expounded in detail in this paper. The computer program has also been written using this method here. Two kinds of radiation heat transfer problems have been simulated with numerical method using the computer program, and the predictions carried out are quite in agreement with the exact results. It shows that the 3-dimensional discrete transfer radiation model is one of the best way to obtain heat flux and temperature in various application.
