Abstract
X-ray microtomography, numerical structure generation, 3D image analysis
and lattice-Boltzmann flow simulations are used in analyzing flow in
fibrous porous materials. We determine the flow permeability and other
flow related parameters for three-dimensional structures given by x-ray
tomographic images of paper samples, and also for structures generated
by the PAKKA fibre-deposition model. Comparison with experimental
permeabilities is included. Properly combined, the novel experimental
and numerical methods utilized here can provide very effective tools for
the study of various structural and transport properties of paper,
board and paper-making fabrics.
