The Effects of Periodicity Assumptions in Porous Media Modelling

T. O. M. Forslund, I. A. S. Larsson, J. G. I. Hellström, T. S. Lundström
2021 Transport in Porous Media  
AbstractThe effects of periodicity assumptions on the macroscopic properties of packed porous beds are evaluated using a cascaded Lattice-Boltzmann method model.  ...  For unsteady flows, it is found that one unit cell is not enough to represent all structures of the fluid flow which substantially impacts the permeability and dispersive properties of the porous bed.  ...  Therefore pore-scale simulations of unsteady flows require a domain larger than a single unit cell to accurately model the porous media.  ...
