In a carbon sequestration system CO2 would be pumped down a well and into a reservoir at supercritical temperatures and pressures. An important consideration is the long term stability of the reservoir. The goal of these simulations is to thermally model the injection well and investigate the temperature gradient developed in the cap rock. Ultimately, results from this study will lead to an ...

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 approach based on Darcy’s law. To test the capabilities of the COMSOL Multiphysics modeling platform, we ...

Partial melting occurs beneath mid-ocean ridges in Earth's mantle and the resulting liquid migrates to the surface to form a new oceanic crust. In this system, mass can be exchanged between the liquid and solid phases through melting and solidification and, at the high temperatures and pressures associated with the Earth's interior, the solid matrix deforms through the process of compaction, ...
Modelling the Thermal Impact of a Repository for High-Level Radioactive Waste in a Clay Host Formation
Belgian Nuclear Research Centre (SCK-CEN), Waste & Disposal Department, Mol, Belgium
Disposal in deep clay geological formations is one of the promising options for disposal of high-level radioactive waste. Yet, they can generate considerable amounts of heat as a side effect of radioactive decay. This paper shows how COMSOL Multiphysics has been used to evaluate the physical impacts of the heating on the geological media around a deep disposal system. The software was found ...

Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward. According to the deep-seated spreading model, both the volcanic edifice and its uppermost basement are spreading eastwards because of magma inflation processes related to a dike complex located at a depth between the summit craters and the Valle del ...

We use 3D numerical models to analyze the ground deformation observed at Long Valley Caldera (LVC) between 1992 and 2000 via space-based geodetic techniques. More specifically, we implement a complex model that includes the topography and the material heterogeneities information of LVC. The 3D heterogeneous models are implemented of COMSOL models in a Genetic Algorithm optimization to constrain ...

In a soil pore, water flows through the biofilm, where the density of the latter was assumed to represent a flow resistance. This mechanism was implemented as a local change of fluid viscosity proportional to local biofilm density. It was assumed that diffusive substrate transport is possible through the biofilm region such that the biofilm was able to degrade the substance. Maximum flow ...

We present an implementation of the Structural Mechanics module of COMSOL Multiphysics to model the state of stress associated with the emplacement of large volcanic edifices on the surface of a planet. These finite element models capture two essential physical processes: (1) Elastic flexure of the lithosphere beneath the edifice load, and (2) Pressurization of a magma-filled chamber that serves ...

This study investigates the feedback between fault slip and dike intrusions during the Mono-Inyo eruption sequence of ~1350 A.D. (Mono Basin, California). We perform an extensive validation of 3D finite element models, implemented in the Structural Mechanics module of COMSOL Multiphysics, against standard analytical solutions of fault dislocation in a homogeneous elastic flat halfspace. The ...

In this work, COMSOL Multiphysics was used to develop a model to investigate the degree of saturation in sloped terrain. The model was validated via laboratory experiments incorporating Lan’s man-made rainfall slope model test. The validated model was used in an actual case study to simulate the Maokong Landslide.
