Abstract:In this paper, a finite element (FE) based model for the viscous and incompressible fluid flow through a regular porous media composed of rigid (immobile) particles/fibres is considered, and an analytical-numerical approach is employed to calculate the associated transverse permeability. The effects of an iotropy, i.e. the particle shape or orientation, as well as porosity, i.e. the volume fraction, on the overall permeability are discussed in detail. The results from this study can be used for verification and validation of advanced models for particle-fluid interaction and for the coupling of the discrete element method (DEM) with FEM or CFD.
