| 摘 要： | 利用Ｍｏｎｔｅ－Ｃａｒｌｏ方法和Ｚｏｎｅ方法相结合的数值计算方法分析各向同性散射介质中的辐射换热．首先利用所编程序对一维平板系统的吸收－散射介质的半球反射率和半球透射率分别进行了计算，并与有关文献的结果作了比较，获得满意的结果．然后对三维封闭方腔内介质的辐射换热进行了计算，获得了在定常内热源下均匀的吸收－发射－散射介质的温度场和壁面辐射热流．

| Abstract: | Monte-Carlo method is combined with Zone method to analyze radiative heat transfer in isotropically scattering media. Considering one-dimension system of slabs, the hemispherical reflectiv- ity and the transmissivity are calculated with the special program, which agree well with the existing values. In a three dimensional enclosure system, its temperature distribution and wall flux are also calculated when the system is subject tq a constant heat source. |
