Reduction of chaotic particle transport driven by drift waves in sheared flows
(AMER INST PHYSICS, 2008)
Investigations of chaotic particle transport by drift waves propagating in the edge plasma of tokamaks with poloidal zonal flow are described. For large aspect ratio tokamaks, the influence of radial electric field profiles ...
Plasma torch for supersonic plasma spray at atmospheric pressure
(2016-11-01)
This work presents a plasma torch able to operate at supersonic regime with axial injection of feedstock. In contrast to commonly used linear scheme, the principal axis of the plasma torch is perpendicular to feedstock ...
Recurrence quantification analysis of turbulent fluctuations in the plasma edge of Tokamak Chauffage Alfveacuten Breacutesilien tokamak
(AMER INST PHYSICS, 2010)
Recurrences are close returns of a given state in a time series, and can be used to identify different dynamical regimes and other related phenomena, being particularly suited for analyzing experimental data. In this work, ...
Solid-state hydrolysis of postconsumer polyethylene terephthalate after plasma treatment
(2013-02-05)
Plasma treatments were applied on the surface of postconsumer polyethylene terephthalate (PET) bottles to increase their wettability and hasten the subsequent hydrolysis process. Sixty-four treatments were tested by varying ...
Numerical Study of Particle Heating in a Plasma Jet
(2017-03-01)
The motion of particles axially injected into the plasma spray process has been studied using a one-dimensional model. The effect of the initial particle velocity and particle diameter on the final particle velocity and ...
Effect of the admixture of N2to low pressure, low temperature H2-CH4-CO2microwave plasmas used for large area deposition of nanocrystalline diamond films
(2020-11-04)
In a distributed antenna array reactor, microwave H2-CH4-CO2 plasmas with admixture of N2 used for the low-temperature deposition of nanocrystalline diamond (NCD) films are studied by in situ infrared laser absorption ...
Comparison Between Conventional And Transferred Dbd Plasma Jets For Processing Of Pdms Surfaces

Numerical simulation of magnetic-field-enhanced plasma immersion ion implantation in cylindrical geometry
(Institute of Electrical and Electronics Engineers (IEEE), 2006-08-01)
Recent studies have demonstrated that the sheath dynamics in plasma immersion ion implantation (PIII) is significantly affected by an external magnetic field. In this paper, a two-dimensional computer simulation of a ...
Analytical solutions for Tokamak equilibria with reversed toroidal current
(AMER INST PHYSICS, 2011)
In tokamaks, an advanced plasma confinement regime has been investigated with a central hollow electric current with negative density which gives rise to non-nested magnetic surfaces. We present analytical solutions for ...
