Parallel Simulations of Underground Flow in Porous and Fractured Media

In this paper, we present a parallel software for solving linear flow equations in two kinds of subsurface media, a 2D highly heterogeneous porous medium and a 3D fracture network. Parallel computing allows us to solve very large linear systems improving the realism of simulations. For these two applications, we perform a scalability analysis of two parallel solvers : HYPRE and PSPASES. HYPRE i...

HPC Fluid Flow Simulations in Porous Media Geometries

The simulation of ows in porous media on the microscale level requires a high number of unknowns to resolve the geometry of the ssures in-between the sand grains. For the geometric representation of the sand grains we use fracture network-like structures in 2D and sphere packings in 3D. These geometries are created with an in-house scenario generator, based on a modi ed and extended version of ...

Coupling Fluid Flow with Porous Media Flow

The transport of substances back and forth between surface water and groundwater is a very serious problem. We study herein the mathematical model of this setting consisting of the Stokes equations in the fluid region coupled with the Darcy equations in the porous medium, coupled across the interface by the Beavers–Joseph–Saffman conditions. We prove existence of weak solutions and give a compl...

Multi-scale high-performance fluid flow: Simulations through porous media

In petroleum production and engineering, the subsurface formation that surrounds the well screen gets, in many cases, deteriorated with time in relation to its hydraulic conductivity. As a consequence, well production declines with time and this limits to a large extent its efficiency. Since well installation is a major production operation that usually requires a large capital, it is always im...

An Immersed Boundary Method for Computing Heat and Fluid Flow in Porous Media

A volume-penalizing immersed boundary (IB) method is presented that facilitates the computation of fluid flow in complex porous media. The computational domain is composed of a uniform Cartesian grid, and solid bodies are approximated on this grid using a series of grid cells (i.e., a “staircase” approximation). Solid bodies are distinguished from fluid regions using a binary phase-indicator fu...
