摘要
本文建立了蒙特卡洛法模拟散射参与性介质内辐射传递计算模型。对蒙特卡洛法的计算精度及运行时间进行了较为详细的分析,提出了几种判断计算精度的方法。同时,借助蒙特卡洛法模拟辐射传递过程,进行数值“辐射实验”。利用该“实验结果”进行了物性反问题研究。在已知光学厚度的前提下,得到散射反照率与后半球辐射热流之间的单值函数关系。
The Monte-Carlo (MC) model for radiative transfer in scattering participating medium is developed in this paper. The precision and CPU time of MC model are analysed and several characters are employed to estimate the uncertainty of MC simulation. In meanwhile, by the MC numerical radiative transfer experiment, the radiative property inverse problem has been studied. The monotropic function between scattering albedo and backward radiative flux has been deduced, when the optical thickness is well known.
