A set of X-ray tomographic images of a highly porous material composed of air-saturated coconut fibers isconsidered and used to estimate intrinsic characteristics of the material. Two physical properties are ofinterest: porosity and static airflow resistivity. For the porosity, two-dimensional... Ver mais
