    A model may be defined as a simplified version of the real porous medium system and the transport phenomena that occur in it. Because the model is a sim­ plified version of the real system, no unique model exists for a given porous medium system.

Most contributions to this subject deal with flow situations, where density and viscosity changes in the fluid are neglected. This restriction may not always be justified. The models presented in the book demonstrate immpressingly Author: Ekkehard O. Holzbecher. Finally, we model the density-driven flows with chemical reactions as well as the evolution of the pore structure to investigate the interplay of density contrast, chemical reactions, and the evolution of the porous media.

We begin with simulating density-driven flows without chemical reaction at the fluid-solid interface, i.e., Da = 0. In fluid mechanics, fluid flow through porous media is the manner in which fluids behave when flowing through a porous medium, for example sponge or wood, or when filtering water using sand or another porous material.

As commonly observed, some fluid flows through the media while some mass of the fluid is stored in the pores present in the media.

This includes, but is not limited to: saturated/unsaturated flow, multiphase flow, multicomponent reactive transport, heat transfer and coupled hydraulic, thermal, mechanical, chemical and biological processes. Fractures within a porous media effect the flow properties through the porous matrix.

The Fracture Flow interface solves for pressure on internal (2D) boundaries within a 3D matrix, based on a user-defined aperture. The computed pressure is automatically coupled to the physics describing the porous media flow in the surrounding matrix, an approximation that saves time and computational.

Existing analytical and semianalytical solutions for density‐driven flow (DDF) in porous media are limited to 2‐D domains. In this work, we develop a semianalytical solution using the Fourier Galerkin method to describe DDF induced by salinity gradients in a 3‐D porous enclosure.

The goal of this research is to investigate the influence of fracture networks on this benchmark problem due to the great importance of the fractured heterogeneity effect on unstable DDF.

For this aim, the fractured Elder problem is solved using COMSOL Multiphysics. A hydromechanical model with explicit fracture flow is presented for the fully coupled analysis of flow and deformation in fractured porous media. Extended finite-element method (XFEM) was utilized to model the fracture discontinuity in the two-dimensional plane-strain mechanical model.Get this from a library!
