A Prediction of Energy Piles’ Long-Term Operation Using a Coupled Thermo-Hydro-Geomechanical Model

T. Vu [1], L. Medina [1], D. de la Cruz [1], J. Ramirez [1], B. Xu [1]
[1] University of Texas - Rio Grande Valley, Edinburg, TX, USA

An energy pile harvests geothermal energy to heat and cool a building by integrating ground heat exchanger (GHX) pipes into the building’s deep foundation, and extracts heat from the ground in the winter to heat buildings and injects heat into the ground during the summer. In areas with ... En savoir plus

Towards a Quantitative Prediction of Ice Forming at the Surface of Airport Runways

J. D. Wheeler [1], P. Namy [1], M. Rosa [1], L. Capobianco [1],
[1] SIMTEC, Grenoble, France

Anticipation of meteorological events such as ice forming is a key challenge to optimise the use of antifreeze on airport runways. To obtain a predictive numerical tool of ice forming on the runways, Groupe ADP and SIMTEC developed a COMSOL Multiphysics® model, in which several physical ... En savoir plus

A 3D Multiphase Flow Model of Hydrogen Storage in Geological Formations

E. Abarca [1], A. Sainz-Garcia [1], F. Grandia [1],
[1] Amphos 21 Consulting S.L., Barcelona, Spain

Renewable energies generate temporary mismatches between energy demand and supply. The conversion of surplus energy to hydrogen and its storage in geological formations is one option to balance this energy gap. Storage in deep saline aquifers is the most cost-effective option for ... En savoir plus

Implication of COMSOL® to Laser Powered Non-Isothermal Reactors for Pyrolysis in the Gas Phase

D. Kekejian [1], L. Khachatryan [2], M. Barekati-Goudarzi [3], D. Boldor [3],
[1] Department of Physics and Astronomy, Louisiana State University, Baton Rouge, LA, USA
[2] Department of Chemistry, Louisiana State University, Baton Rouge, LA, USA
[3] Department of Biological & Agricultural Engineering, Louisiana State University Agricultural Center, Baton Rouge, LA, USA

The IR CO2 laser powered chemical conversions in the gas phase are intriguing and the researchers’ attention was focused on this transformation a while ago. The method, known as Infrared Laser Powered Homogeneous Pyrolysis, or IR LPHP opened reaction pathways not reached by conventional ... En savoir plus

Building a Robust Numerical Model for Mass Transport Through Complex Porous Media

J. Perko[1], D. Mallants[1], E. Vermariën[2], and W. Cool[2]
[1]Belgian Nuclear Research Centre (SCK-CEN), Mol, Belgium
[2]Belgian Agency for Radioactive Waste and Enriched Fissile Material (ONDRAF/NIRAS), Mol, Belgium

Mass transport modelling through porous media is typically characterized by complex physics and geometry. In the particular case of radionuclide transport, modelling for radioactive waste repositories, an additional level of complexity, and thus uncertainty, originates from the long time ...

Modeling Internal Erosion Processes in Soil Pipes

J. L. Nieber [1], G. V. Wilson [2], G. A. Fox [3],
[1] University of Minnesota, St. Paul, MN, USA
[2] United States Department of Agriculture - Agricultural Research Service National Sedimentation Laboratory, Oxford, MS, USA
[3] North Carolina State University, Raleigh, NC, USA

The erosion of the interior of soil pipes is an important process in the fields of geomechanics and geomorphology. Soil pipes can form in water holding structures like dams and levees, and water flow through these structures becomes concentrated into the soil pipes as they evolve by the ... En savoir plus

Geologic Carbon Storage: Implications of Two-Phase Flow on Injection-Induced Stress on Faults

S. Prasun [1], S. Kim [2], S. A. Hosseini [3],
[1] Louisiana State University, Baton Rouge, LA, USA
[2] Department of Civil Engineering University of Nebraska - Lincoln, Omaha, NE, USA
[3] Bureau of Economic Geology, University of Texas - Austin, Austin, TX, USA

Geologic carbon storage that involves injecting carbon dioxide (CO2) into a subsurface sequestration site provides the vital approach for reducing CO2 emissions into atmosphere and thus addressing climate change issue. One challenge associated with CO2 geologic storage is that pore ... En savoir plus

Damage Simulation of Fracture Asperity in Geothermal Systems

C. Zeng [1], W. Deng [1],
[1] Missouri University of Science and Technology, Rolla, MO, USA

Mechanical simulation at one pair of asperity contact has been conducted using the COMSOL Multiphysics® software and the Structural Mechanics Module to study the sliding friction of rock fractures surface as real fracture surface contact slides driven by pressure solution. The evolving ... En savoir plus

Lithosphere-Scale 3D Thermal Models of the Norwegian Continental Shelf

Y. P. Maystrenko [1],
[1] Geological Survey of Norway (NGU), Trondheim, Norway

To reveal key features of the thermal pattern at different structural levels of the Norwegian continental shelf and the adjacent mainland, the lithosphere-scale 3D structural models have been used to represent a structure of the sedimentary cover, underlying crystalline crust, and ...

3D Modeling of the In-Situ Stress Field in Nordland, Northern Norway

S. Gradmann [1], Y. Maystrenko [1], M. Keiding [1], O. Olesen [1],
[1] Geological Survey of Norway, Trondheim, Norway

Investigating the unusual neotectonic activity in northern Norway provides a number of challenges since both far-field and near-field stresses need to be considered. The far-field background stress strongly controls the overall stress regime. The regional stress field stems from the ... En savoir plus
