While several studies have linked network and in-fracture scale properties to conservative transport behavior in subsurface fractured media, on reactive cases remain relatively underdeveloped. In this study, we explore the of an irreversible kinetic reaction during interaction two solute plumes, one consisting species A other B. When plumes converge, these react kinetically form a new C via $$A...

Abstract We propose a quality-based optimization strategy to reduce the total number of degrees freedom associated with discrete problem defined over polygonal tessellation Virtual Element Method. The presented Quality Agglomeration algorithm relies only on geometrical properties mesh, agglomerating groups neighboring elements. test this approach in context fractured porous media, which generat...

We present a topology-based method for mesh-partitioning in three-dimensional discrete fracture network (DFN) simulations that takes advantage of the intrinsic multi-level nature DFN. DFN models are used to simulate flow and transport through low-permeability fractured media subsurface by explicitly representing fractures as entities. The governing equations numerically integrated on computatio...

This paper presents several test cases intended to be benchmarks for numerical schemes for single-phase fluid flow in fractured porous media. A number of solution strategies are compared, including a vertex and a cell-centered finite volume method, a non-conforming embedded discrete fracture model, a primal and a dual extended finite element formulation, and a mortar discrete fracture model. Th...

As a new modeling procedure of geothermal energy extraction systems, the authors present two dimensional and three dimensional modeling techniques of subsurface fracture network, based on fractal geometry. Fluid flow in fractured rock occurs primarily through a connected network of discrete fractures. The fracture network approach, therefore, seeks to model fluid flow and heat transfer through ...
