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.
