Title

Radiative Transfer Through an Isotropically Scattering Finite Medium with Reflecting Boundaries

Abstract

An approximate but closed-form solution to the radiative transport equation is used to examine radiative transfer through an isotropically scattering dielectric coating, which has a diffuse substrate and is exposed to collimated and diffuse incident radiation. Simple algebraic expressions are presented for the intensity and flux distribution and for the bidirectional, directional hemispherical, hemispherical directional, and hemispherical reflectances. The simple form of the results makes them attractive for use in combined conduction-radiation heat transfer calculations where non-gray behavior is important. Results are presented to demonstrate the influence of refractive index, scattering albedo, optical thickness, incident angle, and surbstrate reflectance. 15 refs.
