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 ... En savoir plus

Bentonite is a versatile material that is, among other things, envisaged in designs for radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydraulic-mechanically coupled process of bentonite saturation is commonly based on two-phase flow and a ... En savoir plus

Vacuum infusion processes are well adapted for large composites parts and, therefore, widely used for the manufacturing purposes in several applications fields such as aviation or naval industry. Simply speaking single plies or a given fibrous reinforcement is pre-shaped and positioned ... En savoir plus

Hydrogen has great potential to be the fuel of the future through utilization in fuel cells, but it is rarely found naturally and must be produced in energy-intensive processes. Steam reforming, the process of heating natural gas and steam in the presence of a catalyst to drive a ... En savoir plus

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 ... En savoir plus

We present a detailed 2D COMSOL Multiphysics® model used to determine and improve the conversion efficiency in a liquid-metal microfluidics-based portable energy transducer. To date, most work on power generation technologies has focused on the optimization of existing technologies, and ... En savoir plus

Current and emerging energy storage devices need to be enhanced to cope with the energy and power density requirements of different applications. Electrochemical models are helpful tools for the development and redesign of existing Li-ion batteries as well as to support more innovative ... En savoir plus

Design of latent heat energy storage systems (LHESS) requires knowledge of heat transfer processes within them, as well as the phase change behavior of the phase change material (PCM) use. COMSOL Multiphysics can be used to model (LHESS). Natural convection plays a crucial role during ... En savoir plus

Advancements in simulation technology are supported by rapidly evolving enablers such as Cloud infrastructure, high-performance computing platforms (on & off-premises), on-demand Machine Learning systems, and secure multi-user environments. These advancements provide an opportunity ... En savoir plus

Penning-trap mass spectrometers are the tools of choice for mass-ratio measurements of two different single ions with highest precision. The investigated ions are stored consecutively in a combination of an electric quadrupole potential and a homogeneous magnetic field at ultra-high ... En savoir plus
