Bayesian Learning of Gas Transport in Three-Dimensional Fracture Networks
Yingqi Shi, Donald J. Berry, John Kath +9
Modeling gas flow through fractures of subsurface rock is a particularly challenging problem because of the heterogeneous nature of the material. High-fidelity simulations using di…
Characterizing the impacts of multi-scale heterogeneity on solute transport in fracture networks
Matthew R. Sweeney, Jeffrey D. Hyman, Daniel O'Malley +4
We model flow and transport in three-dimensional fracture networks with varying degrees of fracture-to-fracture aperture/permeability heterogeneity and network density to show how…
Impact of artificial topological changes on flow and transport through fractured media due to mesh resolution
Aleksandra A. Pachalieva, Matthew R. Sweeney, Hari Viswanathan +3
We performed a set of numerical simulations to characterize the interplay of fracture network topology, upscaling, and mesh refinement on flow and transport properties in fractured…
Flow and Transport in Three-Dimensional Discrete Fracture Matrix Models using Mimetic Finite Difference on a Conforming Multi-Dimensional Mesh
Jeffrey D. Hyman, Matthew R. Sweeney, Carl W. Gable +3
We present a comprehensive workflow to simulate single-phase flow and transport in fractured porous media using the discrete fracture matrix approach. The workflow has three primar…
Variable resolution Poisson-disk sampling for meshing discrete fracture networks
Johannes Krotz, Matthew R. Sweeney, Jeffrey D. Hyman +2
We present the near-Maximal Algorithm for Poisson-disk Sampling (nMAPS) to generate point distributions for variable resolution Delaunay triangular and tetrahedral meshes in two an…
Maximal Poisson-disk Sampling for Variable Resolution Conforming Delaunay Mesh Generation: Applications for Three-Dimensional Discrete Fracture Networks and the Surrounding Volume
Johannes Krotz, Matthew R. Sweeney, Carl W. Gable +2
We propose a two-stage algorithm for generating Delaunay triangulations in 2D and Delaunay tetrahedra in 3D that employs near maximal Poisson-disk sampling. The method generates a…
