Natural groundwater flow can increase the efficiency of geothermal system. But groundwater flow is not available everywhere. A patented new idea is to use air injection well to create artificial flow in sandy or gritty soils. The governing equations of fluid flow and heat transfer ... Read More
The bentonite barrier is an essential part of a safe spent fuel repository in granitic bedrock. In this work COMSOL Multiphysics® is used in modelling the Thermal (T), Hydrological (H), Mechanical (M) and Chemical (C) phenomena and processes taking place in a bentonite buffer. Special ... Read More
Modeling soil water dynamics requires an accurate description of soil hydraulic properties, i.e. the retention and hydraulic conductivity functions. Generally, these functions are assumed to be unchanged over time in most simulation studies. In this paper, we implemented temporal changes ... Read More
A benchmark study was carried out by the Swiss Nuclear Safety Inspectorate (ENSI) in collaboration with the Laboratory for Waste Management (LES) of the Paul Scherrer Institute (PSI) in order to evaluate the capabilities of the program COMSOL for the calculation of the transport of ... Read More
Advances in visualization and discretization of pore structures by means of Computed Tomography, and rapidly increasing computational capabilities, allow numerical modeling of pore-scale fluid flow based on the incompressible Navier-Stokes equations rather than using a macroscopic ... Read More
The method to derive upscaled expressions for the dispersion coefficients for reactive flow in a porous medium uses a periodic unit cell (PUC), which consists for instance of a spherical grain in a cube, but nothing prohibits defining more complex PUC's. Homogenization leads to a coupled ... Read More
We combine the potentiality of COMSOL with Monte Carlo optimization procedures, referred to as Simulated Annealing and Genetic Algorithm, in order to analyze and interpret ground deformation measured in active volcanic areas. Through MATLAB® subroutines, we use FE (Finite Element) ... Read More
Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward. Three contrasting models have been proposed: deep-seated spreading, shallow sliding and tectonic block movements. In order to better understand the ... Read More
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 ... Read More
Using 2D viscoelastic plane strain models we investigate the dependency of the stress field of slabs on geometry and kinematics of subduction zones (relative velocity of interacting plates and their absolute velocity with respect to the mantle). We conclude that the concentration of Von ... Read More
