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 کاملSimulating Transport and Geochemical Evolution of Acid Mine Drainage through Discretely Fractured Porous Media
A modelling study is performed to assess the evolution of acid mine drainage (AMD) in fractured subsurface environments using two simulation methods: the equivalent porous medium (EPM) and the discrete-fracture network (DFN) approach. The 2D simulations are conducted using the numerical flow and reactive transport model POLYMIN (Molson et al. 2005) based on a mixed silicate-carbonate host rock ...
متن کاملApplicability of Averaged Concentrations in Determining Geochemical Reaction Rates in Heterogeneous Porous Media
This work examines the applicability of averaged concentrations, a mathematical analog of field-measured solute concentrations averaged over a large number of pores, in determining mineral reaction rates in heterogeneous porous media. Pore-scale network models were used to represent sandstones with anorthite and kaolinite as reactive minerals that are heterogeneously distributed in space. React...
متن کاملNumerical simulation of non-isothermal multiphase tracer transport in heterogeneous fractured porous media
We have developed a new numerical method for modeling tracer and radionuclide transport through heterogeneous fractured rocks in a non-isothermal multiphase system. The model formulation incorporates a full hydrodynamic dispersion tensor, based on three-dimensional velocity ®elds with a regular or irregular grid in a heterogeneous geological medium. Two dierent weighting schemes are proposed f...
