Multi-Scale permeability of particulate and porous media

چکیده
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/fibers is considered, and an analytical-numerical approach is employed to calculate the associated transverse permeability. The effects of an isotropy, 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.

The permeability and tortuosity of pore-scale two and three-dimensional random porous media were calculated using the Lattice Boltzmann method (LBM). Effects of geometrical parameters of medium on permeability and tortuosity were investigated as well. Two major models of random porous media were reconstructed by computerized tomography method: Randomly distributed rectangular obstacles in a uni...

Simulating fluid flow at micro level is an ongoing problem. Simplified macroscopic flow models like Darcy’s law is unable to estimate fluid dynamic properties of porous media. The digital sample reconstruction by high resolution X-ray computed tomography scanning and fluid-dynamics simulation, together with the increasing power of super-computers, allow to carry out pore-scale simulations throu...
متن کاملExperimental Investigation of the Permeability and Inertial Effect on Fluid Flow through Homogeneous Porous Media
The value of the permeability in fluid flow through porous media is important for process investigation. In low Reynolds number, the classic Darcy’s law is suitable for simulation of fluid flow. In this paper, an experimental study for evaluation of preformed fiber permeability has been done. Also, the deviations from the classical Darcy law by experimental and numerical simulation of the N...
