A Modeling Approach for Simulating Geothermal Energy Utilization by Borehole Heat Exchangers and Borehole Heat Exchanger Arrays

Michael Rembe1
1Rembe Consulting PartG mbB, Germany

Decarbonization of the heating sector requires the exploitation of climate-neutral energy sources and the use of natural heat storage. Shallow and deep geothermal energy can make a valuable contribution to this. The dimensioning and design of geothermal boreholes and larger borehole heat ... Read More

Numerical Modeling of Bentonite Erosion due to Sedimentation in Sloping Fractures

Virginia Cabrera1, Arnau Pont1, Andrés Idiart1, Patrik Sellin2
1Amphos 21 Consulting S.L., Barcelona, Spain
2SKB, Solna, Sweden

The study of bentonite erosion mechanisms in fractures is a problem of maximum interest to understand the long-term performance of the engineered barrier in deep geological repositories of spent nuclear fuel. In this context, erosion due to shear by seeping water, sedimentation due to ... Read More

FEM Model Highlights Clues of Surface Deformation Pattern at Campi Flegrei Caldera

Pierdomenico Romano1, Prospero De Martino1, Bellina Di Lieto1, Annarita Mangiacapra1, Zaccaria Petrillo1
1Istituto Nazionale di Geofisica e Vulcanologia, “Osservatorio Vesuviano”, Italy

Campi Flegrei Caldera is an active volcano located westward of Naples, Italy. Despite its volcanic activity spanning over 39,000 years, the area is densely populated and poses a significant threat to the inhabitants due to ongoing seismicity, ground uplift, and hydrothermal activity ... Read More

Modeling Strategy of a Large Field of Shallow Borehole Heat Exchangers

E. Meneses Rioseco1, M. Dussel1, I. S. Moeck1
1Georg-August-Universität Göttingen, Lower Saxony, Germany

Transforming the energy sector worldwide towards renewable, climate-neutral energy sources requires innovative ideas and excellent engineering solutions. In particular, shallow geothermal energy utilization is currently showing a remarkable development. In highly urbanized regions, large ... Read More

Efficient Geothermal Cooling in Harsh Environments: A Combined Experimental and Modelling Approach

Mohammed Al-Azba1, Ahmed Abotaleb2
1Qatar Environment and Energy Research Institute, HBKU, Qatar Foundation, Doha, Qatar
2ICube Laboratory, Université de Strasbourg-CNRS, 67000 Strasbourg, France

In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... Read More

Implications of Sorption on Carbon Dioxide Sequestration in Gas Shales

K Arunachalam1, X Fan1
1University of Edinburgh, UK

Gas shales are one of the potential sinks considered for carbon dioxide sequestration. Therefore further research on the importance of sorption on the carbon dioxide sequestration potential is highly topical. Experimentally measured maximum sorption capacity of carbon dioxide was about ... Read More

An alternative equation-based model in COMSOL Multiphysics® for bentonite re-saturation

Michael Kröhn1, Lars Fromme2
1GRS gGmbH, Brunswick, Lower Saxony, Germany
2Bielefeld University of Applied Sciences, Faculty of Engineering and Mathematics, Bielefeld, Germany

Bentonite is a versatile material that is, among other things, envisaged in designs for radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydraulic-mechanically coupled process of bentonite saturation is commonly based on two-phase flow and a ... Read More

Numerical Modelling of the Membrane Polarization Effect for Realistic Shapes of the Pore Space

N. Resay1, A. Hördt1
1Technische Universität Braunschweig, IGEP, Braunschweig, Germany

The Spectral Induced Polarization (SIP) is a promising electrical method, which can be used to predict the saturated hydraulic conductivity of consolidated and unconsolidated porous media. It is important to investigate how the SIP response is affected by the shape and distribution of ... Read More

Coupling PEST/PEST++ and COMSOL Multiphysics® for hydrogeophysical model calibration using pilot points

Andres Gonzalez Quiros1, Jean-Christophe Comte1
1University of Aberdeen, Aberdeen, Scotland, UK

The calibration of groundwater models is usually limited by the scarcity of direct hydraulic data. The estimation of heterogeneous distribution of hydraulic properties can be improved through a joint or coupled inversion in which the calibration dataset is complemented with geophysical ...

Numerical Simulation of Field-Scale Landfill Gas Emission

Y. Feng1, J. Eun1
1University of Nebraska-Lincoln, Lincoln, NE, USA

Controlling the odiferous landfill gas (LFG) [e.g., Hydrogen sulfide (H2S)] emission is an important environmental issue during operating a municipal solid waste (MSW) landfill. A combination of LFG collection system and landfill cover has been an adapted method to mitigate the issue ... Read More
