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 ...

This study presents the simulation of transport phenomena in the Horstberg geothermal system in the North German Basin. The Horstberg geothermal system composed of a subsurface reservoir and a borehole. The borehole was completed in a multilayer sandstone reservoir and an induced hydraulic fracture was created by massive water injection. During reservoir life time, the warm water will be ...
Hydro-Mechanical Coupling in Saturated and Unsaturated Soils and its Consequences on the Electrical Behaviour

The consequences of hydromechanical coupling on the electrical conductivity of saturated and unsaturated soils are investigated experimentally and numerically. Simulations of the consolidation problem under vertical load for an elastic medium and of the coupled flow of two immiscible fluids have been performed in order to check the capability of electrical resistivity tomography to reconstruct ...

The geomechanical effects related to CO2 injection into the Krechba formation at In Salah, Algeria, are considered through a coupled modeling approach to simulate simultaneously CO2 migration in the aquifer and the surrounding formations, as well as the poro-elastic stress changes occurring during injection. The model is based on the simultaneous resolution of the governing equations for two ...

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import “realistic structures” from geologic samples scanned by means of computer tomography (CT) as stl-files into COMSOL ...

This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for containment of hazardous waste such as radiocesium-contaminated MSW generated by Fukushima Daiichi nuclear ...

The Effect of the Disintegration of Chemical Stratification on the Time-dependent Behavior of the Earth’s Mantle
A. Galsa, and M. Herein
Based on recent results from seismology, geochemistry etc. the distinct chemical character of the D’’ layer (lowest part of the mantle around the Earth’s core) has appeared unequivocally. Numerical calculations have been carried out to investigate the effect of the disintegration, mixing and homogenization of the dense D’’ on the time-dependent behavior of mantle convection. A ...

This paper reports on the application of COMSOL Multiphysics’ Richard\'s Equation Interface in the assessment of irrigation moisture sensors for detecting the level of water saturation in a spatial variably saturated soil. The Richard\'s Equation (in COMSOL) provides the interface which automates the van Genuchten equation. A hypothetical soil column 4m by 4m was set up with seven irrigation ...

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 underground hydrogen storage (Lord et al., 2014). A 3D multiphase flow model in a dome shaped geological formation ...
