COMSOL Multiphysics, TOUGHREACT and Numerrin Comparison in Some Modelling Tasks of Spent Nuclear Fuel Disposal

A. Itälä[1], V-M. Pulkkanen[1], M. Laitinen[2], M. Tanhua-Tyrkkö[1], and M. Olin[1]
[1]VTT Technical Research Centre of Finland, Espoo, Finland
[2]Numerola Oy, Jyväskylä, Finland

Bentonite clay is used as a protecting barrier around both the copper capsules in deposition holes and in deposition tunnels in the KBS-3 final disposal concept for spent nuclear fuel. The performance of these bentonite barriers will be investigated both experimentally and by modelling. ... Mehr lesen

Evaluation of CO2 Leakages From An Aquifer Storage

A. Thoraval[1], R. Farret[2], A. Cherkaoui[2], and P. Gombert[2]
[1]INERIS, Nancy, France
[2]INERIS, Verneuil, France

This paper presents preliminary estimations of CO2 overpressure into the reservoir and CO2 leakage through the caprock and the overburden. A simple, two-phase flow model in porous media based on Darcy’s law was used, in order to explore easily long time periods. The models produced by ... Mehr lesen

Numerical Inversion of Surface Deformation at Long Valley Caldera (California) By Using 3D Mechanical Models

S. Pepe, P. Tizzani, and A. Manconi
IREA-CNR, Napoli, Italy

We use 3D numerical models to analyze the ground deformation observed at Long Valley Caldera (LVC) between 1992 and 2000 via space-based geodetic techniques. More specifically, we implement a complex model that includes the topography and the material heterogeneities information of LVC. ... Mehr lesen

Earthquake and Volcano Clustering at Mono Basin (California)

D. La Marra[1], A. Manconi[2], and M. Battaglia[1]
[1]Dept of Earth Sciences, University of Rome “La Sapienza”, Roma, Italy
[2]IRPI-CNR, Strada delle Cacce, Torino, Italy

This study investigates the feedback between fault slip and dike intrusions during the Mono-Inyo eruption sequence of ~1350 A.D. (Mono Basin, California). We perform an extensive validation of 3D finite element models, implemented in the Structural Mechanics module of COMSOL ... Mehr lesen

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 ... Mehr lesen

Integrated Model For Ocean Waves Propagating Over Marine Structures On A Porous Seabed

D-S. Jeng, X. Luo, and J. Zhang
Division of Civil Engineering, University of Dundee, Dundee, Scotland, UK

In this paper, an integrated model for ocean waves propagating over a submerged coastal structure, based on COMSOL Multiphysics, is presented. In the model, Navier-Stoke Equation is solved for the wave propagation and Biot’s poro-elastic model is solved for the porous seabed. The new ... Mehr lesen

Coupled Hydro-Mechanical Analysis of Excavation Damaged Zones around an Underground Opening in Sedimentary Rock

H. Abdi[1], E. Evgin[1], M. Fall[1], T.S. Nguyen[2], and G. Su[2]
[1]University of Ottawa, Ottawa, ON, Canada
[2]Canadian Nuclear Safety Commission, Ottawa, ON, Canada

A large amount of research work has been carried out in many countries to determine the viability of radioactive waste disposal in deep geological repositories. It is well known that excavation can cause damage around underground openings. On the other hand, the mechanical damage can ... Mehr lesen

Modeling Horizontal Ground Heat Exchangers in Geothermal Heat Pump Systems

A. Chiasson
University of Dayton, Dayton, OH, USA

Geothermal heat pumps use the earth as a heat source and sink via a ground heat exchanger (GHX) that consists of a network of buried heat exchange pipes, which can either be installed in vertical boreholes or in shallow horizontal trenches or excavations. The main goal in GHX design is ... Mehr lesen

Coupled Models of Lithospheric Flexure and Magma Chamber Pressurization at Large Volcanoes on Venus

G. Galgana[1], P. McGovern[2], and E. Grosfils[2]

[1]Lunar and Planetary Institute, Houston, Texas, USA
[2]Pomona College, Claremont, California, USA

We present an implementation of the Structural Mechanics module of COMSOL Multiphysics to model the state of stress associated with the emplacement of large volcanic edifices on the surface of a planet. These finite element models capture two essential physical processes: (1) Elastic ... Mehr lesen

Effect of S-p Relation Model on DNAPL Migration Simulation Result

H. Ishimori[1], and K. Endo[1]
[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

To consider effective counter measures against ground water contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models to ... Mehr lesen
