The subsurface thermal regime has been investigated in boreholes from southern Norway. During the purely conductive 2D thermal modeling, the COMSOL Heat Transfer for Solids interface has been used to simulate heat transfer by heat conduction. COMSOL physics interfaces Heat Transfer in ... 詳細を見る

High Voltage Direct Current transmission (HVDC) is a suitable alternative for long distance transmission. During the years, the use of this technology has been increasing, which is one of the several reasons to improve methodologies in HVDC grounding systems. Unlike the usual approach ... 詳細を見る

The Swedish Nuclear Fuel and Waste Management Company (SKB) operates the underground repository for low- and intermediate-level nuclear waste (SFR) located in Försmark, Sweden. An extension of the SFR is planned to accommodate mainly waste arising from the decommissioning of Swedish ... 詳細を見る

Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of ... 詳細を見る

In the context of increasing demographic pressures around the world, soil improvement techniques constitute viable alternatives to expensive foundations. Among these techniques, the biocalcification of granular soils appears as a promising alternative relying on the formation of calcium ... 詳細を見る

Electromagnetic sounding measurements utilize magnetic induction to constrain the interior geophysical properties of planetary bodies. Under some conditions, the Earth’s moon can be approximated by the response of a conducting sphere in a vacuum. Transient magnetic fields originating ... 詳細を見る

Topographic effects on magnetotelluric responses may be severe on rugged terrains. Finite elements simulation is a valuable tool to quantify this effect, due to its capability to match real morphologies. To do the estimate of the distortion, the AC/DC Module of COMSOL has been employed, ... 詳細を見る

The objective of this study is to acquire a full characterization of a hyper-elastic material. The process is realized by performing a Dynamic Mechanical Analysis (DMA) with a viscoelastic material, which is extended by image processing algorithms in order to measure the changing ... 詳細を見る

A pile transfers structural load to the ground at the surface of its shaft and at its toe. In the calculation of these two components of load, both the deformation characteristics and the strength properties of the soil are needed. In unsaturated soils, matric suction changes the stress ... 詳細を見る

Standing column wells (SCW) are open-loop geoexchange systems used to provide space heating and cooling to buildings. As they use groundwater as heat carrier fluid and modify its thermo-chemical conditions along the year, they may favor calcite dissolution and precipitation, thus ... 詳細を見る
