Effect of Parallel Strip Water Source Spacing on Lateral Infiltration Flux

[1] University of Minnesota, Minneapolis, MN, USA

This analysis evaluates the importance of the lateral component of flow on the infiltration of water from parallel strip sources of water on the soil surface. Flow from such sources will be two-dimensional, having both vertical and lateral components. Here we examine the effect of the spacing between parallel strip sources and the texture of the soil on the rate of infiltration through a given ...

In a carbon sequestration system CO2 would be pumped down a well and into a reservoir at supercritical temperatures and pressures. An important consideration is the long term stability of the reservoir. The goal of these simulations is to thermally model the injection well and investigate the temperature gradient developed in the cap rock. Ultimately, results from this study will lead to an ...

Hydro-Mechanical Modelling of Infiltration Test for a Bentonite-Sand Mixture: Model Verification and Parameter Identification

M. Hasal[1], R. Hrtus[1], Z. Michalec[1], R. Blaheta[1]
[1]Institute of Geonics AS CR, Ostrava, Czech Republic

The first aim of our work is to create a hydro-mechanical model (HM) of unsaturated fluid flow in bentonite-sand mixture (BSM) MX-80. The second aim is to validate and calibrate the developed model by using the data from a laboratory infiltration test of BSM. The used multi-physics model combines Richards type unsaturated flow with diffusive vapour flow and (nonlinear) elastic response of the ...

Geomagnetic Modeling with COMSOL Multiphysics® Software - new

G. Ha[1], S. S. Kim[1], J. H. Kim[1]
[1]Chungnam National University, Daejeon, Korea

Here we aim to advance geomagnetic modeling approaches using COMSOL Multiphysics® software and improve the degree of detail that can be obtained from the measured magnetic field. First, we carried out benchmark tests by comparing the computed results using the widely used analytic solutions for rectangular bodies with arbitrary direction of magnetization with those from the AC/DC Module of ...

State of Stress of Subducting Slabs from Viscoelastic Plane Strain Numerical Modelling

E. Carminati[1] and P. Petricca[1]
[1]Dipartimento di Scienze della Terra, Università di Roma La Sapienza, Roma, Italy

Using 2D viscoelastic plane strain models we investigate the dependency of the stress field of slabs on geometry and kinematics of subduction zones (relative velocity of interacting plates and their absolute velocity with respect to the mantle). We conclude that the concentration of Von Mises stress is controlled by the geometry (curvature) of the slab and that downdip compression in subducting ...

Modelling of Transport Phenomena and Effect of Applied Electrical Field on Heavy Metals Recovery during Application of the Electro-remediation Process

A. Mahmoud, and J. Beaugrand
Laboratoire de Thermique Energétique et Procédés, ENSGTI, Pau, France

A mathematical model for the simulation of contaminant such as heavy metals removal from soils by electric fields was performed in a 2-D geometry using COMSOL Multiphysics. Electrokinetic phenomena is the result of the coupling between hydraulic and electrical potential gradients in fine grained soils. The model describes the coupled transport of mass and charge of species subjected to an ...

Modeling CO2 storage Using Coupled Reservoir-Geomechanical Analysis

T.I. Bjørnarå, F. Cuisiat, E. Aker, and E. Skurtveit
Norwegian Geotechnical Institute(NGI), Oslo, Norway

The geomechanical effects related to CO2 injection into the Krechba formation at In Salah, Algeria, are considered through a coupled modeling approach to simulate simultaneously CO2 migration in the aquifer and the surrounding formations, as well as the poro-elastic stress changes occurring during injection. The model is based on the simultaneous resolution of the governing equations for two ...

An Innovative Reactive Transport Modeling Approach for the Chemical Evolution of a HLW Cell in the Callovo-Oxfordian Formation

J. Molinero[1], D. García[1], M. Grivé[1], A. Nardi[1]
[1]Amphos 21 Consulting, Barcelona, Spain

Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of storage is based on a clay formation with low permeability, homogeneity and continuity (i.e Callovo-Oxfordian ...

Using COMSOL for the Transport Modelling of Some Special Cases in a Bentonite Buffer in a Final Repository for Spent Nuclear Fuel

[1]VTT, Technical Research Centre of Finland, Espoo, Finland

The bentonite barrier is an essential part of a safe spent fuel repository in granitic bedrock. In this work COMSOL Multiphysics® is used in modelling the Thermal (T), Hydrological (H), Mechanical (M) and Chemical (C) phenomena and processes taking place in a bentonite buffer. Special interest lies in systems in which the density of bentonite or bentonite pore water varies. Typically, variation ...

Use of COMSOL as an Educational Tool Through its Application to Ground Water Pollution
