在这项工作中，蒙特卡罗方法被应用于调查的热辐射到外部的基础区域的有限的圆柱形分散的吸收，发射和各向异性散射粒子。该分析假设了氧化铝分散体的散射函数特性。探照灯效应，即由粒子散射到周围环境的室发射辐射，通过允许辐射源自云底部的黑色圆形表面以及云内部来引入。结果表明，各向异性散射和探照灯效应在这种几何结构的传热中起着重要的作用。
In this work the Monte Carlo method is applied to investigate thermal radiation to the exterior base region of a finite cylindrical dispersion of absorbing, emitting, and anisotropically scattering particles. The analysis assumes a scattering function characteristic of aluminum oxide dispersions. Searchlight effect, chamber emitted radiation scattered by the particles to the surroundings, is introduced by permitting the radiation to originate from a black circular surface at the base of the cloud, as well as from within the cloud. The results obtained show that anisotropic scattering and searchlight effect play important roles in heat transfer in this geometry.
