混合模拟方法分析散射介质的辐射换热
Using Hybrid Method to Analyze Radiative Heat Transfer of Isotropic Scattering Media
【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.
