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

Arc welding is a widely used process in heavy industry for the assembly of metallic components. To ensure high-quality welds, it is essential to understand both the welding process and the complex interactions within the melt pool. Numerical simulation is employed as a predictive tool to ...

A novel type of tunable surface acoustic waves (SAW) filter based on 1D phononic crystal controlled by electric is field proposed. The tunability of proposed filter varied over a wide range: 1-20%. Basic idea is electrical controlled induced periodical domains in ferroelectric film based ... En savoir plus

Lorentz Force Velocimetry (LFV) is a non-contact measurement technique used to determine flow rates in electrically conducting fluids by exposing the flow to an external magnetic field and measuring the Lorentz force acting on the magnet system. Typically, for LFV applications real and ... En savoir plus

This paper deals with the simulation study using COMSOL on the deformation of drop-within-drop system in a high intensity oscillating electric field. It consists of a composite drop suspended in a continuous phase. This composite drop has a smaller inner drop suspended within the larger ... En savoir plus

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

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 ...

Problem Description Sorption heat storage systems are attracting growing interest due to their high energy density and loss-free heat storage capability, making them a promising solution for storing surplus solar energy in summer for use in winter in residential buildings. However, these ... 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 WaveEL buoy developed by the company Waves4power is characterized as a point absorber and has a 36 meters long vertical cylinder where a water-piston is oscillating due to induced motion from the waves. Estimating the wave loads on the piston is a challenge due to the presence of ... En savoir plus
