ABSTRACT Three-dimensional radiative heat transfer in a finite medium will be studied theoretically and experimentally. The emphasis of the investigation is to determine the effects of multiple scattering and polarization in media that contain Mie-scattering particles. The theoretical work will involve solving the vector radiative transport equation written in terms of the Stokes parameter and the scattering phase function expressed by a 4x4 phase matrix. Double Fourier transform will be used to transform the transport equation into one-dimensional form and the resulting equation will be solved by Ambartsumian's method. Back-scattered radiation from a medium composed of latex microspheres suspended in distilled water will be measured and the results will be used for model validation.

摘要 有限介质中的三维辐射传热将在理论和实验上进行研究。 研究的重点是确定介质中含有米氏散射粒子的多重散射和偏振效应。 理论工作将涉及解决矢量辐射传输方程的斯托克斯参数和散射相函数表示的4x4相位矩阵。 双傅立叶变换将用于将输运方程转换为一维形式，并且所得方程将通过Ambartsumian方法求解。 将测量由悬浮在蒸馏水中的乳胶微球组成的介质的后向散射辐射，结果将用于模型验证。
