Effects of Anisotropic Scattering on Steady One-Dimensional Radiative Heat Transfer through an Absorbing-Emitting Gray Medium
TLDR
In this article, the effects of anisotropic scattering on temperature distribution of a steady one-dimensional radiative heat transfer through an absorbing, emitting gray medium in a semi-infinite space are analyzed by method of matched asymptotic expansions.Abstract:
Effects of anisotropic scattering on temperature distribution of a steady one-dimensional radiative heat transfer through an absorbing, emitting gray medium in a semi-infinite space are analyzed by method of matched asymptotic expansions. An external radiation beam is imposed through a transparent boundary. Rayleigh scattering is considered as a typical model of an anisotropic scattering. The medium is assumed to be non-heat conducting, not to move and to have constant physical properties, The results show that no qualitative difference is shown between the temperature distribution in a scattering medium and that in a non-scattering medium. Only a little quantitative difference is shown for various values of the beam angle. The difference is in 10 percent of the non-scattering value at most.read more

A multi-dimensional differential approximation for absorbing/emitting and anisotropically scattering media with collimated irradiation☆
Michael F. Modest,S. Tabanfar +1 more
TL;DR: In this article, the authors considered the intensity within a medium to consist of a collimated and a fairly diffuse part, and the overall problem of radiative transfer was reduced to two simpler ones: first the collimated intensity is obtained (equivalent in complexity to a nonscattering medium); for the evaluation of the diffuse part of the radiation (due to emission and scattering), a new differential approximation has been developed.
