Poroelasticity Benchmarking for FEM on Analytical Solutions
We examine the poroelastics mode, which couples hydraulics and mechanics by some basic benchmarks. For cases with analytical solutions we check the accuracy for changing meshes and calculate the convergence rate. En savoir plus
Electromagnetic Well Logs Simulated with the COMSOL® RF Module on a Cluster
Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show that ... En savoir plus
Safe Storage Parameters During CO2 Injection Using Coupled Reservoir-Geomechanical Analysis
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 ... En savoir plus
Computation of the Longitudinal Dispersion Coefficient in an Adsorbing Porous Medium Using Homogenization
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 ... En savoir plus
Modeling Cavity Growth in Underground Coal Gasification
Underground coal gasification (UCG) has received renewed interest due to its potential for utilization of the vast amounts of coals available in deep underground seams and the current drive towards clean coal utilization. UCG process involves the reaction between air/steam and coal in ... En savoir plus
An Extension of Lauwerier’s Solution for Heat Flow in Saturated Porous Media
One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and ... En savoir plus
Integrated Model For Ocean Waves Propagating Over Marine Structures On A Porous Seabed
In this paper, an integrated model for ocean waves propagating over a submerged coastal structure, based on COMSOL Multiphysics, is presented. In the model, Navier-Stoke Equation is solved for the wave propagation and Biot’s poro-elastic model is solved for the porous seabed. The new ... En savoir plus
Modeling of Ultrasonic Transducers and Ultrasonic Wave Propagation for Commercial Applications Using Finite Elements with Experimental Visualization of Waves for Validation
Finite element (FE) modelling of ultrasonic propagation using COMSOL Multiphysics® simulations can be used to create images of waves. Unfortunately, in time-stepping solutions, it is possible for numerical instabilities to grow large and dominate the solution adversely. Any design of ... En savoir plus
A Coupled Analysis of Heat and Moisture Transfer in Soils
This paper is a part of a study on energy piles for heating and cooling of buildings. Energy piles are used for two reasons: (1) to transfer structural loads to foundation soils, and (2) to transfer heat from foundation soils to the building for space heating in winter time and for ...

Simulation of Brine Reflux and Geothermal Circulation in Large Carbonate Platforms: An Attempt to Predict Dolomite Geo-Bodies
Significant volumes of the worlds proved reserves are in dolostone reservoirs. Scope for recovery and success/upside of new exploration plays depend on the chances of encountering dolostone reservoirs with good reservoir properties. Although dolostones make excellent reservoirs in ... En savoir plus
