The disposal of highly radioactive waste in geological environment is not the possibility studies anymore as the countries such as Finland, Sweden, France with more advanced radwaste disposal programs are actually implementing it nowadays. In such disposal system, passive safety does not ... En savoir plus

The increasing demand for large battery packs, driven by the expanding markets for electric vehicles (EVs) and grid-scale energy storage system, necessitates the development rapid battery pack development pipelines such as simulation. We present an integrated multiscale simulation ... En savoir plus

Effectively storing hydrogen in solid form using metal hydrides requires careful attention to thermal management challenges due to the exothermic nature of hydrogen absorption in metal hydrides [1], [2]. The generated heat during this process must be efficiently removed to achieve ... En savoir plus

The low-temperature electrochemical conversion of CO₂ to ethylene offers significant potential for reducing the chemical industry’s reliance on fossil fuels. Despite recent advancements, the key performance indicators—activity, selectivity, and durability—are insufficient for industrial ... En savoir plus

A Solid Oxide Fuel Cell (SOFC) can convert the chemical energy of a fuel (H2-rich gas mixture [1] or syngas [2, 3] or biogas [4]) in electric and thermal energies with high electric efficiency. It is composed of two porous gas diffusion electrodes and an electrolyte (Figure 1). The fuel ... En savoir plus

Due to the increase on the academic and industrial interest on thermal energy storage (TES) systems, the EU Horizon project HYSTORE is developing 4 different solutions. In these solutions, the use of thermochemical materials (TCM) and phase-change materials (PCM) are proposed. We ... En savoir plus

The aim of this work is to compute the mechanical forces in a 12-pulse converter transformer winding in different short-circuit modes. A 12-pulse converter transformer is a three phase transformer with two secondary windings whose tension have 30° phase displacement and one primary ... En savoir plus

The Z-pinch (or zeta pinch) is a type of plasma confinement system used in fusion power research. It relies on an electric current discharge within the plasma to generate a magnetic field that compresses the plasma, creating conditions conducive to nuclear fusion. The concept of Z-pinch ...

Splitting a 3D model into two coupled components can increase performance [1]. Two offshore applications with the AC/DC module and the heat transfer module are presented, but the approach is general. The examples simulate the hotspot temperature in a three core cable with cross-sectional ... En savoir plus

The activity focuses on improving the overall performance and design of a small-sized heat exchanger. This heat exchanger is designed to raise the temperature of a fluid (water), using tubular electric heaters. The device consists of a steel case with two hydraulic connections for fluid ...
