Benchmarking Tailored Formulations of Multiphase Flow in Porous Media

Á. Sainz [1,2], A. Nardi [1], E. Abarca [1], F. Grandía [1]
[1] Amphos 21 Consulting S.L., Barcelona, Spain
[2] Université Toulouse III - Paul Sabatier, Toulouse, France

Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of ... Read More

An Equivalent Kd-based Radionuclide Transport Model Implemented in COMSOL Multiphysics® Software

O. Silva [1], E. Abarca [1], J. Molinero [1], U. Kautsky [2]
[1] Amphos 21 Consulting, Barcelona, Spain
[2] Swedish Nuclear Fuel and Waste Management Co., Stockholm, Sweden

Radionuclide sorption is often simulated using a lumped approach where retention processes are represented by the distribution coefficient (Kd), which relates the radionuclide mass retained in the solid phase to its aqueous concentration. Classical Kd-based simulations rely on two strong ... Read More

Simulation of a Nozzle in a Borehole

E. Holzbecher [1], F. Sun [2],
[1] German University of Technology in Oman, Muscat, Oman, Germany
[2] Georg-August-Universität, Göttingen, Germany

In boreholes nozzles have to be found advantageous to increase the infiltration rate of water into the subsurface ground. Studies and practice in the field shows that the infiltration of water into permeable aquifers can be improved, if the flow in the borehole is modified. Due to the ... Read More

Effect of Parallel Strip Water Source Spacing on Lateral Infiltration Flux

M. García-Serrana [1], J. L. Nieber [1], J. S. Gulliver [1],
[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 ... Read More

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 ... Read More

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

Modeling of Biocalcification in Non-Saturated Conditions

B. Courcelles [1], C. Raymond-Poirier [1],
[1] École Polytechnique de Montréal, Montréal, QC, Canada

In the context of increasing demographic pressures around the world, soil improvement techniques constitute viable alternatives to expensive foundations. Among these techniques, the biocalcification of granular soils appears as a promising alternative relying on the formation of calcium ... 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

Modeling and Simulation of the Consolidation Behaviour of Cemented Paste Backfill

L. Cui [1], M. Fall [1],
[1] University of Ottawa, Ottawa, ON, Canada

In underground mining operations, the mined-out spaces (called stopes) need to be backfilled to maintain the stability of surrounding rock mass and increase the ore recovery. Cemented paste backfill (CPB), a mixture of water, binder, and tailings, has been intensively utilized in ... Read More

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 ... Read More
