Reactive Transport with Fluid–Solid Interactions in Dual-Porosity Media

Contaminant transport in dual-porosity media with dissolved organic matter and bacteria present as mobile colloids.

In riverbank filtration, contaminant transport is affected by colloidal particles such as dissolved organic matter (DOM) and bacterial particles. In addition, the subsurface heterogeneity influences the behavior of contaminant transport in riverbank filtration. A mathematical model is developed to describe the contaminant transport in dual-porosity media in the presence of DOM and bacteria as m...

Time analysis of the three characteristic behaviours of dual-porosity media. I: fluid flow and solute transport

Homogenisation of consolidation and compressible fluid flow in dual-porosity media has highlighted the existence of three characteristic macroscopic behaviours. These three behaviours are, namely, a dual-porosity description which includes memory effects, a single-porosity description with which the micro-porosity is simply ignored, and an intermediate behaviour which we refer as behaviour with...

Hybrid models of reactive transport in porous and fractured media

Darcy-scale models of flow and transport in porous media often fail to describe experimentally observed phenomena, while their pore-scale counterparts are accurate but can be computationally prohibitive. Most numerical multiscale models, which seek to combine these two descriptions, require empirical closures and/or assumptions about the behavior of pore-scale quantities at the continuum (Darcy...

Time Space Domain Decomposition and Reactive Transport in Porous Media

In this paper we present some results concerning the application of timespace domain decomposition methods for reactive transport problems. One of the main objectives of our study is to design local time stepping strategies in order to concentrate numerical efforts on the most reactive part of the domain. This work is a part of the French ANR SHPCO2 project concerning high performance simulatio...
