Microstructural Effects on the Fluid Transport in Fibrous Media

Abstract

A numerical approach is presented for computing the macroscopic permeability of fibrous porous media taking into account for various fiber types in hexagonal arrangement. A model based on Lattice Boltzmann Method(LBM) for viscous, incompressible flow through a regular array of fibers is employed for predicting the permeability of this media. The effect of porosity on the macroscopic permeability is studied. Such microstructure parameter as fiber shape is varied. The results show that the fiber shape significantly affects the permeability of this media in different porosity.
