| 摘 要： | 将谱带模型与有限体积解法相结合；求吸收、发射、散射性非灰介质圆柱体内辐射传递方程。考虑辐射强度场与热扩散温度场的耦合，将控制容积法与有限体积法结合，求解辐射与导热耦合换热。经与光线踪迹法、离散传递法的计算结果比较表明，谱带模型与有限体积解法相结合能处理多场耦合下非灰介质内的辐射换热。

| Abstract: | The combined radiation-conduction heat transfer in the cylindrical semi-transparent medium is simulated by using finite volume method and spectral band model. The simulation results are compared with those of the ray tracing method and the discrete transfer method, respectively. The numerical simulation results indicate that the finite volume method and spectral band model is suitable to deal with coupled radiation-conduction heat transfer of non-gray medium. |
