Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... En savoir plus

Radiofrequency discharges in Hydrogen have a range of applications. In particular, they are used as high-intensity sources of atoms for fundamental and material processing applications. In this study, we investigate a small volume, low pressure RF discharge used to produce Hydrogen ... En savoir plus

Thermal decomposition of plastic waste results in gas products, mainly hydrocarbon molecules (C2-C6), which cannot be released to the atmosphere for environmental reasons. Here, we propose a secondary gas treatment to decompose the hydrocarbon gas products into smaller molecules by ... En savoir plus

Atmospheric-pressure plasma jets (APPJ) are devices that generate chemically reactive species and operate at atmospheric pressure and ambient temperature for a wide range of applications. Plasmas jets produce charged particles (electrons and ions), neutral metastable species, radicals, ... En savoir plus

A power supply is generally used in many electrical devices. In order to deliver uniform power irrespective of time variation, most plasma equipment also uses a power source. Therefore, the power condition in plasma simulations is essential. In time-dependent models using a current ... 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 ...

Plasma torches are used in processing of materials and in energy industry for producing plasma. In this work we use the Equilibrium DC Discharge physics interface of COMSOL Multiphysics® to model a DC non- transferred arc plasma torch, under hypothesis of local thermodynamic equilibrium. ...

In this study, plasma processing parameters of a dielectric barrier discharge (DBD) based argon plasma was carried at atmospheric pressure in flat plate configuration. The time dependent one-dimensional plasma module was adapted for modeling of the DBD in copper electrodes with quartz ... En savoir plus

Finite elements using COMSOL Multiphysics have been used to simulate the edge plasma in a large area capacitively coupled RF reactor. In order to reduce numerical difficulties simplified reactor edge geometries have been used. First results show the importance of electrostatic double ... En savoir plus

The state of the art technology is moving towards more complex and multidisciplinary processes and systems. There is a growing interest in using Multi-physics simulations to have a better understating of the underpinning science of the processes as well as providing cost-effective ... En savoir plus
