The influence of highly anisotropic Mie scattering on radiative heat transfer is investigated. Exact solutions for temperature distributions and radiative flux are found for scattering functions with up to 35 terms in their Legendre polynomial series expansion. Approximation by linear anisotropic scattering is found to describe radiative transfer excellently as long as the phase function is relatively smooth and as long as there is only insignificant backscattering. The linear-anisotropic differential approximation also yields very accurate results (within its limitations) and can account for backscattering as well.
