Transverse permeability of fibrous porous media.
In this study, the transverse permeability of fibrous porous media is studied both experimentally and theoretically. A scale analysis technique is employed for determining the transverse permeability of various fibrous matrices including square, staggered, and hexagonal arrangements of unidirectionally aligned fibers, as well as simple two-directional mats and simple cubic structures. In the pr...
متن کاملAnalytical determination of viscous permeability of fibrous porous media
In this study, the permeability of ordered fibrous media towards normal and parallel flow is determined analytically. In this approach, porous material is represented by a ‘‘unit cell” which is assumed to be repeated throughout the media. Several fiber arrangements including: touching and non-touching arrays are considered. Modeling 1D touching fibers as a combination of channel-like conduits, ...
متن کاملMicrostructural effects on the permeability of periodic fibrous porous media
An analytical-numerical approach is presented for computing the macroscopic permeability of fibrous porous media taking into account their micro-structure. A finite element (FE) based model for viscous, incompressible flow through a regular array of cylinders/fibers is employed for predicting the permeability associated with this type of media. High resolution data, obtained from our simulation...
متن کاملPermeability of microscale fibrous porous media using the lattice Boltzmann method
The permeabilities of microscale fibrous porous media were calculated using the multiple-relaxation-time (MRT) lattice Boltzmann method (LBM). Two models of the microscale fibrous porous media were constructed based on overlapping fibers (simple cubic, body-centered cubic). Arranging the fibers in skew positions yielded two additional models comprising non-overlapping fibers (skewed simple cubi...
متن کاملNumerical analysis of viscous flow through fibrous media: a model for glomerular basement membrane permeability.
Viscous flow through fibrous media is characterized macroscopically by the Darcy permeability ( K D). The relationship between K D and the microscopic structure of the medium has been the subject of experimental and theoretical investigations. Calculations of K D based on the solution of the hydrodynamic flow at fiber scale exist in literature only for two-dimensional arrays of parallel fibers....
