Non Linear Mechanical and Poromechanical Analyses: Comparison with Analytical Solutions

Ecole des Mines
Parc de Saurupt, France

The long-term behaviour of the underground excavations is a social and economic challenge particularly in the contexts of post-mining or radioactive waste storage. Numerical modelings are currently used to understand and forecast the complex behaviour of rock mass around the underground cavities. In order to accurately perform these multiphysics modelings at high space and time scales, it is ...

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 including a fluid flow component, in COMSOL Multiphysics simulation environment. The latter is modeled on a ...

Geothermal systems represent a large resource that can provide, with a reasonable investment, a very high and cost-effective power generating capacity. Despite its unquestionable potential, geothermal exploitation has long been perceived as limited, mainly because of the dependence from strict site-related conditions, mainly related to the reservoir rock’s permeability. In this work, SP ...

Safe Storage Parameters During CO2 Injection Using Coupled Reservoir-Geomechanical Analysis

T.I. Bjørnarå[1], E. Aker[1], and E. Skurtveit[1]
[1]NGI, Oslo, Norway

Safe short term storage of CO2 depends mainly on structural and solubility trapping. On longer term, mineral trapping is also contributing to the trapping of CO2. To be able to investigate the importance of these different storage mechanisms, a finite element model for simulation of CO2 injection has been developed in COMSOL Multiphysics®. The model describes and solves for two-phase flow ...

Numerically Generated g-functions for Ground Coupled Heat Pump Applications

[2]Dime, University of Genova, Genova, Italy

Ground-coupled heat pumps (GCHP) are successfully installed since at about 20 years in many countries to fulfill space conditioning requirements in building applications. In most cases the heat pump is connected to a system of vertical ground heat exchangers (as illustrated in Figure 1) where a fluid is circulated inside a system of pipes inserted in a deep borehole drilled in the soil. Drilling ...

微波加热煤岩裂隙变形的电-热-固耦合模型

管伟明 [1], 聂欣 [1],
[1] 新疆大学,乌鲁木齐,新疆,中国

为研究不同加热方式下煤岩内部裂隙在热力耦合作用下的变形特征,建立了微波和常规加热两种数值模型,考查了不同温度场分布特征下裂隙周边应力应变场的变化过程。研究结果表明:微波加热,温度场分布具有内高外低的特征,此时裂隙周边分布的应力多为压应力,且数值较大,裂隙边界位移表现为向内收缩;常规加热,温度场分布具有外高内低的特性,此时裂隙周边分布应力多为拉应力,但量值较低,裂隙边界位移表现为向外扩张;热源越靠近裂隙压应力越明显,反之拉应力明显。

Düsensauginfiltration (DSI),‘nozzle-suction-infiltration’, is a new method for dewatering that avoids groundwater abstraction from the aquifer. Drawdown is achieved via pumping of groundwater at upper abstraction section, meanwhile, all the pumped water is injected through the same borehole, but in greater depth. We use COMSOL Multiphysics® for the development of a 2D model that simulates ...

The percolation of water into soil can be modeled considering Darcy's Law in laminar flow. In this manner the key property is the coefficient of hydraulic conductivity. Its determination can be made through laboratory or field testing. One of the most known field tests used for determination of this property is the Slug Test. This test consists of a perforated well in the ground where a known ...

[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 reservoir engineering, bio-engineering, environmental engineering etc. We have used quasi-static poroelastic ...

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 lithospheric mantle during a 3D thermal modeling. For the construction of these 3D models, all available geological ...
