Numerical Study on Collision-Less Plasma Sheaths of RF-Glow Discharge

Simulation and Model Reduction Methodsfor an RF Plasma Glow Discharge

In this paper, we report on numerical solutions and model reduction results for a plasma glow discharge model with a radio frequency ionization source. A pseudospectral implementation of a global spectral method was found to give accurate simulation results that correctly reflected the expected physical behavior of an argon plasma under the simulated operating conditions. Numerical residual ana...

RF Glow Discharge Atomic Emission Spectroscopy of Non-Conducting Materials

Numerical Simulation of DC and RF Glow Discharges

As part of an ongoing research effort on plasma actuators for flow control, a numerical study of DC glow discharges and γ-mode RF glow discharges has been carried out. For simplicity, the study focused on two-dimensional problems. Several experimentally observed features of these discharges were reproduced in the numerical computations, including the expansion of the electrode spot with increas...

Influence of operating parameters on surface properties of RF glow discharge oxygen plasma treated TiO₂/PET film for biomedical application.

In this paper, a thin transparent titania (TiO2) film was coated on the surface of flexible poly(ethylene terephthalate) (PET) film using the sol-gel method. The surface properties of the obtained TiO2/PET film were further improved by RF glow discharge oxygen plasma as a function of exposure time and discharge power. The changes in hydrophilicity of TiO2/PET films were analyzed by contact angl...

Glow Discharge Plasma Properties of Gases of Environmental Interest

Experiments in a low pressure glow discharge on gases of environmental relevance: CO2,CO y O2 are reported. We studied the various atomic processes: ionization, excitation and molecular dissociation with typical discharge parameters of p∼0.6 mbar, I≤ 0.1 A and V∼1100 Volts. We used visible and near UV spectroscopy to observe the emitted radiation on both electrodes on pure gases and hydrogen se...
