Hybrid models of reactive transport in porous and fractured media
Darcy-scale models of flow and transport in porous media often fail to describe experimentally observed phenomena, while their pore-scale counterparts are accurate but can be computationally prohibitive. Most numerical multiscale models, which seek to combine these two descriptions, require empirical closures and/or assumptions about the behavior of pore-scale quantities at the continuum (Darcy...
متن کاملPore scale simulation of solute transport in fractured porous media
[1] We investigate the effects of the porosity (and thus permeability) of porous matrix and the fracture aperture on transport in fractured porous media. We do so with detailed lattice Boltzmann simulations on constructed porous media with a single fracture. Both plume spatial moments (the average plume velocity and the dispersion coefficients) and mass transfer coefficients between the facture...
متن کاملModelling flow and solute transport in fractured porous media
A BEM numerical model is presented for the flow and solute transport in fractured porous media, which is based on the dual reciprocity method multi domain scheme (DRM-MD). The model solves the 3D flow equation based on the Darcy law in the coupled system of porous media, fracture network and fracture intersections. Unlike the discrete fracture models, which for simplicity use Fick's law in the ...
متن کاملLarge-scale Mass Transport Modelling in Discretely- Fractured Porous Media
A numerical model has been developed for the large-scale simulation of solute transport in discretelyfractured porous media. A generic finite elements code, MEF++, has been used to account for simultaneous flow and transport in 2D fracture and 3D porous medium elements. Equations for the fractures and the porous medium are solve separately but are coupled with a mass transfer term. This mass tr...
متن کاملA Tvd Method for Contaminant Transport in Porous Media
The objective of this work is to present a numerical study of contaminant migration in saturated porous media. For this purpose, the advection-difussion equation describing the evolution of contaminant plumes in a vertical cross section of an aquifer is discretized employing a Total Variation Diminishing method (TVD), which provides an efficient way to eliminate spurious numerical oscillations ...
