Abstract

This paper deals with a pseudo-continuous model for the prediction of radiation transfer in fibrous media. The proposed model incorporates the fiber orientation and effective fiber length for the determination of the radiative properties of the media. Applicability of the model in the prediction of radiative properties of fibrous media is justified on the basis of experimental findings. In this study, a planar fibrous medium in which every fiber is oriented parallel to the boundaries stratifying the medium is adopted as a test specimen. The radiation scattered from a single fiber taken out of the medium is first measured to determine the complex refractive index of the fiber material. The experimentally determined complex refractive index of the fiber material is then used to predict the radiative properties of the medium. The radiation transfer in the specimen calculated by using the predicted radiative properties is seen to agree well with the corresponding experimental results.
