COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows consideration of mantle compressibility using the CFD Module and I benchmarked COMSOL Multiphysics using ...

Presented work is motivated by pre-realization phase of rock heating experiment in underground, testing properties for cyclic energy storage. Heating unit, installed in large borehole from end of a tunnel, is fixed to the rock face with the geo-polymer. Rest of the borehole is filled with isolation material. We used the Heat Transfer Module and the Structural Mechanics Module in COMSOL for ...

The Swedish Nuclear Fuel and Waste Management Co (SKB) is responsible for final disposal of spent fuel and radioactive waste. SKB operates SFR, an underground waste repository in crystalline rock. The evolution of groundwater flow within the repository needs to be estimated considering different options for the design of the engineered barriers. The goal is to predict the effects of flow and ...

Seismic evaluation of existing dams is a major issue that has been even more highlighted by the recent events in Italy. In this regard, researchers and engineers need a reliable and quick tool to assess the complex behaviour of the structure – fluid – soil system. In this paper the soil-structure interaction for concrete gravity dams is considered, investigating its effect on the dynamic ...

We use GPS measurements and Finite Element analysis to investigate strain accumulation in the interaction between active fronts of the Southern Alps and Dinarides at the northern edge of the Adriatic micro-plate. We develop a three dimensional model of the area taking into account the regional topography, approximating the crust as an elasto-plastic medium and reproducing as close as possible ...

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 ...

Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosified water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three scenarios, i.e., (1) pure water injection, (2) constant polymer viscosified water injection and (3) polymer slug ...

The erosion of the interior of soil pipes is an important process in the fields of geomechanics and geomorphology. Soil pipes can form in water holding structures like dams and levees, and water flow through these structures becomes concentrated into the soil pipes as they evolve by the process of internal erosion. With time the erosion process will lead to a soil pipe spanning the entire ...

The mass and recoverability of oil and gas in unconventional reservoirs strongly depend on the understanding the petrophysical properties of the rocks at a large range of scales. Three-dimensional imaging is capable of unveiling the detailed microstructures within the rocks down to the nanometer scale. Using a multiscale imaging protocol, a Devonian shale rock sample with heterogeneities is ...

Opalinus clay is currently being proposed as a potential host rock for radioactive waste repository in deep geological formation. It is then important for performance assessments to understand the transport properties of such rocks. Clay materials are characterized by low hydraulic conductivities and diffusion is assumed to be the main transport mechanism. The studied rock is a complex assembly ...
