Solution of Poroelastic Equations with Different Base Variables Using Equation-based Modeling

M. H. Akanda [1], Y. Cao [1], A. J. Meir [1],
[1] Department of Mathematics & Statistics, Auburn University, Auburn, AL, USA

Poroelasticity equations describe the interaction between fluid flow and solids deformation within a porous medium. Modeling of poroelasticity is coupling between elastic deformation of porous materials and Darcy’s law. Poroelasticity has numerous real world applications such as in ... Read More

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 ... Read More

New Thermo-Mechanical Fluid Flow Modeling of Multiscale Deformations in the Levant Basin

M. Belferman [1], R. Katsman [1], A. Agnon [2], Z. Ben-Avraham [1],
[1] The Dr. Moses Strauss Department of Marine Geosciences, Leon H.Charney School of marine sciences. Haifa University, Mt. Carmel, Haifa, Israel
[2] Institute of Earth Sciences, The Hebrew University, Jerusalem, Israel

The Levant has been repeatedly devastated by numerous earthquakes since prehistorical times. In order to understand the role of the dynamics of the water bodies in triggering the deformations in the Levant basin, a new theoretical thermo-mechanical model is constructed and extended by ...

Lava Tubes at Shallow Depth

M. Di Bari, and G. Zito
University of Bari, Italy

Many theoretical studies concerning lava tubes focus on the thermal disturbances generated on the earth surface. Recently a solution was suggested, where a lava tube located at a great depth h in the soil, where the ratio between h to the major axis of the ellipse a is ... Read More

2-Dimensional Incompressible and Compressible Mantle Convection new

Changyeol Lee[1]
[1]Faculty of Earth and Environmental Sciences, Chonnam National University, Gwangju, Republic of Korea

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows ... Read More

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 ... Read More

A 3D Thermal Model for Lunar Surface Using COMSOL Multiphysics® Software: Validation and Results

K. Durga Prasad [1], S.V.S. Murty [1], V. K. Rai [1],
[1] Planetary Sciences Division, Physical Research Laboratory, Ahmedabad, Gujarat, India

A comprehensive three dimensional finite element thermal model has been developed using COMSOL Multiphysics® software to understand the thermo-physical behaviour of the uppermost regolith layer of the moon. The model can simulate variable layers, layer thickness and dimensions and can ... Read More

Coupled Hydrochemical Modeling for the Optimal Design of an In-situ Redox Experiment

P. Trinchero[1], J. Molinero[1], G. Román-Ross[1], A. Nardi[1], L.M. De Vries[1], T. Karvonen[2], P. Pitkänen[3]
[1]Amphos 21, Barcelona, Spain

[3]Posiva, Eurajoki, Finland

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the ... Read More

Permeability in Fragmented Materials and its Application to Underground Mining

S. Palma [1], R. Castro [1], A. Hekmat [1],
[1] Mining Engineering Department, Block Caving Laboratory, University of Chile, Santiago, Chile

The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of ... Read More

TDS-based porous flow modeling in subduction zone

Changyeol Lee [1],
[1] Faculty of Earth Systems and Environmental Sciences, Chonnam National University, Gwangju, Republic of Korea

Slab dehydration and fluid migration in subduction zone is important because it allows us to understand characteristics of the arc volcanism such as migration of the volcano front as well as the global circulation of water and carbon. To minimize the technical difficulties in the ... Read More
