Topographic Effects on Radio Magnetotelluric Simulations on Levees: Numerical Modeling for Future Comparison With Fields Results

R. Duval[1], C. Fauchard[1], R. Antoine[1]
[1]ERA23-IFSTTAR, Laboratoire des Ponts et Chaussées de Rouen, CETE-Normandie Centre, France

We study the topography influence of levees on the electric resistivity signal obtained with the Radio-Magnetotelluric method. Field measurements have been modeled with COMSOL, using the AC/DC and RF Modules. A levee situated in Orléans along the Loire river (France) has been considered ... En savoir plus

Development of a Thermo-Hydro-Geochemical Model for Low-Temperature Geoexchange Applications

F. Eppner [1], P. Pasquier [1], P. Baudron [1],
[1] École Polytechnique de Montréal, Montréal, QC, Canada

Standing column wells (SCW) are open-loop geoexchange systems used to provide space heating and cooling to buildings. As they use groundwater as heat carrier fluid and modify its thermo-chemical conditions along the year, they may favor calcite dissolution and precipitation, thus ... En savoir plus

Implementation of a Modified Anisotropic Creep Model for Clays with Use of the Physics Builder

M. Karlsson [1], J. Yannie [1],
[1] Chalmers University of Technology, Gothenburg, Sweden

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user ... En savoir plus

Analysis of Electromagnetic Propagation for Evaluating the Dimensions of a Large Lossy Medium

A. Pellegrini[1] and F. Costa[1]
[1]ALTRAN Italia, Pisa, Italy

In this paper the propagation of a plane wave in a large lossy medium is presented. The investigated geometry consists in a wedgeshaped lossy dielectric embedded in a lossy material with different electromagnetic properties. The aim of the study is to determine the feasibility of a radar ... En savoir plus

Simulation of Deep Geothermal Heat Production

E. Holzbecher, P. Oberdorfer, F. Maier, and Y. Jin
Georg-August Universität Göttingen
Göttingen, Germany

Geothermal heat production from deep reservoirs (5000-7000 m) is currently examined, not only in Germany. Our reference set-up consists of two pipes within a single borehole: one for pumping. We examine a design, where a single borehole splits into two legs at a certain depth. The two ... En savoir plus

The Effect of the Disintegration of Chemical Stratification on the Time-dependent Behavior of the Earth’s Mantle

A. Galsa, and M. Herein
Eötvös University
Budapest, Hungary

Based on recent results from seismology, geochemistry etc. the distinct chemical character of the D’’ layer (lowest part of the mantle around the Earth’s core) has appeared unequivocally. Numerical calculations have been carried out to investigate the effect of the disintegration, mixing ... En savoir plus

Remote Sensing of Electromagnetically Penetrable Objects: Landmine and IED Detection

R. Eze [1], G. Sivulka [2], ,
[1] City University of New York - LaGuardia Community College, Long Island City, NY, USA
[2] Regis High School, New York, NY, USA

The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to ... En savoir plus

Quantification of Porosity Changes Due to Precipitation of Cement Materials with iCP

[1] Amphos 21 Consulting, Barcelona, Spain
[2] Obayashi Corporation, Tokyo, Japan
[3] Japan Atomic Energy Agency, Gifu, Japan

The Japan Atomic Energy Agency (JAEA) is carrying out an URL (Underground Research Laboratory) project in Mizunami city, central Japan. The project is a purpose-built generic URL project that is planned for a scientific study of the deep geological environment in fractured crystalline ... En savoir plus

Development of COMSOL-Based Applications for Heavy Oil Reservoir Modeling

S. Cambon [1], I. Bogdanov [1]
[1]Open & Experimental Center for Heavy Oil (CHLOE), University of Pau, Pau, France

The efficiency and environmental impact of oil production become a principal challenge of energy producing companies. The improvement of existing and development of novel methods are often feasible within either a “new” physical framework (from the viewpoint of oil reservoir ... En savoir plus

Finite Element-Based Characterization of Viscoelastic Materials

X. Song [1], S. Dircks [1], D. Mirosnikov [1], B. Lassen [2],
[1] Mads Clausen Institute, SDU, Sønderborg, Denmark
[2] DONG Energy, Fredericia, Denmark

The objective of this study is to acquire a full characterization of a hyper-elastic material. The process is realized by performing a Dynamic Mechanical Analysis (DMA) with a viscoelastic material, which is extended by image processing algorithms in order to measure the changing ...
