چکیده
The past decades have witnessed an increasing interest in numerical simulation for flow fractured porous media. To date, most studies focused on 2D or pseudo-3D computational models, where the impact of 3D complex structures seepage has not been fully addressed. This work presents a method modeling heterogeneous structures, typically stochastic discrete fractures and inclusions, are able to be simulated. A mesh strategy is proposed discretize domain. In particular, treatment intersected elements developed ensure conforming mesh. Then, discretization provided, which flux interactions fractures, inclusions surrounding rock matrix included. Numerical tests performed analyze hydraulic characteristics First, framework validated by comparing solutions with results embedded fracture model. Next, effects orientation, aperture radius fluid equivalent permeability tensor analyzed. variations pressure distribution studied homogeneous Finally, properties medium investigated show difference feature between inclusions.

Numerical 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...
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 کاملNano-/Microparticle Tracers for Evaluating Structures in Fractured Porous Media
Nanoand microparticle tracers are expected to be used for evaluating structures in geological developments, however their transport behavior is not well characterized. This study investigated nanoparticle transport in a fractured medium through a microscope. A single fracture and rock matrix (grain and pore space) were fabricated on a silicon wafer, which is called a micromodel. Water and nanop...
