Modelling of non- transferred argon-nitrogen plasma arc and plasma jet

Lattice Boltzmann Computation of Plasma Jet Behaviors : part II Argon-Nitrogen Mixture

In this paper an innovative computational approach, namely the Lattice Boltzmann Method (LBM), is used for simulating and modeling plasma jet behaviors. Plasma jets are a high temperature flows, then all physical parameters are temperature dependent. This work aims to address the issue of simulating plasma-jet from the point of view of extending the applications to simulating flows with tempera...

Effect of Asymmetrical Distribution of Current Density on the Three-Dimensional Non-Transferred Arc Plasma Torch

In this study, three-dimensional steady-state non-transferred arc plasma torch was investigated by computational fluid dynamics (CFD) method with user defined function (UDF). Two-equation current density profile was developed to simulate the complex plasma flow inside the torch. The effect of asymmetric distribution of current density (ADCD), particularly the deviation distance (distance betwee...

Destruction of organo-halogenated compounds by DC non-transferred arc plasma

The actual technologies for the destruction of organo-halogenated substances are reviewed and compared with the emerging plasma processes based on the non transferred arc plasma torches. The associated costs are presented.

Atmospheric Pressure Single Electrode Argon Plasma Jet for Biomedical Applications

Atmospheric pressure single electrode argon /oxygen plasma jet has been generated between a high-voltage electrode and the surrounding room air for treating thermally sensitive materials is reported. The discharge has been characterized by electrical and optical emission spectroscopic technique. The microplasma jet device operated by an electrical power less than 10 W exhibited a long plasma je...
