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 structures generated by the PAKKA fiber deposition model and for three-dimensional structures given by x-ray tomographic images of actual paper samples. Comparison with experimental permeabilities are presented. Properly combined, the novel experimental and numerical methods utilized here can provide unprecedentedly effective tools for the study of various structural and transport properties of paper, board and paper-making fabrics.
