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...
متن کاملModeling nonthermal plasmas generated in glow discharges*
Over the past decade, tremendous progress has been made in the modeling of nonthermal plasmas, and models have now reached the point that they are being used to help guide the experimental optimization of plasma based devices. In this communication we provide an overview of models used to describe nonthermal plasma generated in glow discharges. We show results from two applications, plasma disp...
متن کاملAbsolute Spatially- and Temporally-Resolved Optical Emission Measurements of rf Glow Discharges in Argon
Spatially- and temporally-resolved measurements of optical emission intensities are presented from rf discharges in argon over a wide range of pressures (6.7 to 133 Pa) and applied rf voltages (75 to 200 V). Results of measurements of emission intensities are presented for both an atomic transition (Ar I, 750.4 nm) and an ionic transition (Ar II, 434.8 nm). The absolute scale of these optical e...
متن کاملPulsed RF discharges, glow and filamentary mode at atmospheric pressure in argon
The properties of a pulsed radio frequency capacitive discharge are investigated at atmospheric pressure in argon. The discharge can operate in two different modes: a homogeneous glow discharge or turn into filaments. By pulsing the 13.56 MHz generator both the filamentary and the glow modes can be selected depending on the pulse width and period. For a 5μs pulse width (∼70 RF cycles in the pul...
متن کاملSimulations of Corona and Glow Discharges with Adaptive Cartesian Mesh
Corona discharges exist in a variety of forms (streamer and diffuse, steady and pulsed) and have multi-scale nature (in both space and time). High spatial resolution is required to analyze ionization fronts, streamers and Trichel pulses observed in corona discharges. We present multi-dimensional simulations of corona and glow discharges with adaptive Cartesian mesh using fluid models. Effects o...
