Kirchhoff's and Planck's radiation laws for small particles in scattering atmospheres of flames
Abstract
The correct treatment of thermal radiative emission and absorption by small particles is discussed, and ideas relating to the resolution of the problem are presented. It is noted that the size and shape effects which modify Planck's radiation law for small enclosures and the emission cross section for small particles do not affect the validity of Kirchhoff's radiation laws when applied to macroscopic collections of small particles, such as in scattering atmospheres or flames.
