Several models to estimate the effective thermal conductivity of fibrous layers for radiative heat transfer are compared with these calculated using the Monte Carlo method. The models assuming isotropic scattering are shown to underestimate the effective thermal conductivity, and the model based on the two flux model assuming the Milne Eddington approximation is demonstrated to agree very well with the results obtained using the Monte Carlo method. When the incident radiation to the glass fiber layers has spectral variation, the estimated thermal conductivity obtained assuming that the incident radiation is monochromatic with the peak wave -length differs from the one obtained considering al] the incident spectral variation. For nickel fiber layers, the difference is shown to be 15% or less.
