CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, ... En savoir plus

FT wind sensors measure wind speed and direction using an acoustic field superimposed on a flow field in an acoustic resonator equipped with three piezoelectric transducers. The study proposed here focuses on the acoustic resonance technology of a simplified wind sensor geometry, and how ... En savoir plus

Reducing greenhouse gas emissions and finding new ecological and renewable energy sources are among the biggest challenges humanity is facing nowadays [1] [2]. At the same time, power requirements are increasing constantly, where primary energy consumption is intrinsically accompanied by ... En savoir plus

Nowadays, spot laser welding is a full-fledged part of industrial manufacturing and is routinely used due to its advantages. It generates very located temperature gradients, and therefore, induces small distortions in the pieces. The COMSOL Multiphysics® software is used to model the ... En savoir plus

The continuous inkjet technology is widely used in the industry for marking and coding, and reposes on the emission of charged droplets at high velocity and high frequency. The shape of the droplets and the length needed for the jet breakup are important indicators when designing a ... En savoir plus

High Intensity Focused Ultrasound (HIFU) is used as a noninvasive technique of tissue heating and ablation for different medical treatments. This paper presents a quantitative comparison of HIFU acoustic fields experimentally obtained versus simulated acoustic fields. Acoustic field ... En savoir plus

Started in March 2020, the SOFITT project (Saturated Open-Cell Foams for Innovative Tribology in Turbomachinery), funded by the ANR (French National Research Agency), aims to develop reliable, high-performance, and environmentally friendly solutions for the guidance and support systems ...

Liquid metals are foreseen as a multipurpose coolant in fusion blanket systems. However, the strongly magnetic environment of the fusion reactor hinders the regular flow of the liquid metal. It interacts with transverse magnetic field and produces a Lorentz force opposing the flow, ... En savoir plus

During the evolution of multicellularity, cells needed to find a way to self-organise into structures able to fulfil a broad range of physiological functions. Directed cell migration (DCM) is an elegant way to reorder cells and break symmetry based on simple rules and local information, ... En savoir plus

Simulation of arc-wire additive manufacturing is under development in many academic and industrial sectors and at different scales. The study at the melt pool scale is often interesting to study deposition shapes and defects but not very relevant to calculate the stresses and strains at ... En savoir plus
