Abstract
We present calculations of combined radiative and conductive heat flow in two types of polyester fiber insulation. The radiative transport was represented by both a diffusion model and a two-flux model, and the results compared. Optical parameters in both cases were derived from realistic scattering calculations using the frequency-dependent complex refractive index of polyester and the measured fiber diameter. We found that anisotropy in the scattering must be included in the model to obtain accurate results. Model calculations agreed very well with direct measurements of thermal resistance for samples of several thicknesses, with no adjustable parameters in the theory.
