A theoretical and experimental research program in radiative heat transfer will be performed. The work will deal with multiple scattering in a two-dimensional, cylindrical medium that is exposed to a laser beam. The laser beam is incident normal to the top surface of the scattering medium. Emphasis is placed on understanding the influence of anisotropic scattering in the thin to moderate optical thickness range. The integral equations for the source functions are formulated exactly by using radiative transfer theory, and the expressions for intensity and flux are derived. Supporting experiments will be conducted with spherical latex particles as scattering centers suspended in distilled water.

将进行辐射换热的理论和实验研究计划。这项工作将处理暴露在激光束下的二维圆柱介质中的多重散射。激光束垂直入射到散射介质的顶面。重点是了解各向异性散射在薄到中等光学厚度范围内的影响。利用辐射传递理论，建立了源函数的精确积分方程组，导出了强度和通量的表达式。辅助实验将以悬浮在蒸馏水中的球形乳胶粒子为散射中心。
