Multi-component acoustic characterization of porous media

The acoustic characterization of porous media and its standards

While there is a growing number of methods for the acoustic or elastic characterizations of porous materials, there is only a few test procedures which are standardized. The benefits of using standards are to harmonize procedures and to reduce measurement uncertainties between laboratories. They should, moreover, give guidelines for accurate characterizations of materials and should clearly pre...

Topological Characterization of Porous Media

It is an attractive approach to predict flow and in based on direct investigations of their structure. The most crucial property is the of the structure because it is difficult to measure. This is true both at the pore scale, which may be represented as a binary structure, and at a larger scale defined by continuousmacroscopic state variables as phase density or . At the pore scale a function i...

Multi-scale modelling of two-phase-two-component processes in heterogeneous porous media

Flow and transport phenomena in porous media are the governing processes in many natural and industrial systems. Not only do these flow and transport phenomena occur on different space and time scales, but it is also the porous medium itself which is heterogeneous where the heterogeneities are present on all spatial scales. We consider a large domain with randomly distributed heterogeneities wh...

Probing Multi-Component Transport in Porous Media over a Hierarchy of Length-Scales

Recent Progresses in Lattice Boltzmann Simulations of Flow and Multi-component Reactive Transport in Porous Media

In recent years, the Lattice Boltzmann (LB) method has become a powerful numerical tool for simulating complex fluid flows and modeling physics and chemistry in fluids. Derived from the continuum Boltzmann equation used in statistical mechanics, the LB method has the advantage of describing non-equilibrium dynamics, especially in fluid-flow applications involving interfacial dynamics and comple...
