In view of an energy system based on fluctuating renewable sources, the use of thermal energy storage (TES) systems plays a crucial role. In particular, large-scale underground water-based TES represent a promising solution as demonstrated by a number of cases currently being established ... En savoir plus
When polypropylene (PP) is produced it contains impurities in the form of dissolved gasses. These gasses can be removed by heating the material (in the form of pellets in a silo) and flushing with plenty of fresh air. However, one of the gasses is C9, which is flammable. We built a model ... En savoir plus
Bentonite is a versatile material that is, among other things, envisaged in most countries worldwide for use in radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydro-mechanically (THM) coupled process of bentonite saturation is commonly based ... En savoir plus
High-voltage power cables are vital components of power transmission systems. Submarine cables are critical power carriers between offshore wind farms and onshore ac grids. Moreover, underground cables are generally preferred over overhead installations in land applications, owing to ... En savoir plus
In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... En savoir plus
The simplicity, reliability and low costs of electro-mechanical breakers have made them the workhorse for the interruption of low voltage short-circuit currents. In the presence of a short circuit, the contacts of the breaker heat up, and a bridge of molten metal forms between the pair ... En savoir plus
Friction Stir Welding (FSW) is a solid-state joining technique that has become increasingly popular and efficient for welding both similar and dissimilar metallic materials. Despite its success in joining dissimilar materials, further development is necessary to meet industry ... En savoir plus
The increasing demand for energy and the need to reduce reliance on fossil fuels in response to climate change have spurred the exploration of renewable energy sources. Energy Geostructures address these issues by providing at the same time mechanical support to overlying structures and ... En savoir plus
Microarchitectured materials are generally made of different compounds bound at the microscopic level using a periodic pattern. This results in a macroscopic material with new properties arising from each of the individual compound properties and the way the microarchitecture binds them. ... En savoir plus
HETT22 is a software developed through joint efforts by Deflexional and Heidelberg Materials. It enables construction companies to accurately simulate, plan and monitor heat and strength development in concrete after castings. Leveraging the power of the COMSOL Multiphysics® software, ...
