DC Glow Discharge

DC glow discharges in the low-pressure regime have long been used for gas lasers and fluorescent lamps. DC discharges are attractive to study because the solution is time independent. The 1D and 2D models show how to use the DC Discharge interface to set up an analysis of a positive ... Читать дальше

Dielectric Barrier Discharge

This model simulates electrical breakdown in an atmospheric pressure gas. Modeling dielectric barrier discharges in more than one dimension is possible, but the results can be difficult to interpret because of the amount of competing physics in the problem. In this simple model the ... Читать дальше

Atmospheric Pressure Corona Discharge in Air

This tutorial model presents a study of a coaxial DC corona discharge in dry air at atmospheric pressure. The dimensions and operation conditions are similar to ones found in electrostatic precipitators with wire-to-plate configurations. The inner wire electrode has a 100-mm radius and ... Читать дальше

Inductively Coupled Plasma (ICP) torch

This model investigates the electrical and thermal characteristics of an inductively coupled plasma torch at atmospheric pressure. The discharge is assumed to be in local thermodynamic equilibrium. Читать дальше

In-Plane Microwave Plasma

Wave heated discharges may be very simple, where a plane wave is guided into a reactor using a waveguide, or very complicated as in the case with ECR (electron cyclotron resonance) reactors. In this example, a wave is launched into reactor and an Argon plasma is created. The wave is ... Читать дальше

Atmospheric Pressure Corona Discharge

This model simulates a negative corona discharge occurring in between two co-axially fashioned conductors. The negative electric potential is applied to the inner conductor and the exterior conductor is grounded. The modeled discharge is simulated in argon at atmospheric pressure. Читать дальше

3D ICP Reactor, Argon Chemistry

3D plasma modeling is possible to do in COMSOL. A square coil is placed on top of a dielectric window and is electrically excited at 13.56MHz. A plasma is formed in the chamber beneath the dielectric window, which contains Argon gas at low pressure (20 mtorr). The gas flows into the ... Читать дальше

GEC ICP Reactor, Argon Chemistry

The GEC cell was introduced by NIST in order to provide a standardized platform for experimental and modeling studies of discharges in different laboratories. The plasma is sustained via inductive heating. The Reference Cell operates as an inductively-coupled plasma in this model. ... Читать дальше

Thermal Plasma

This model simulates a plasma at medium pressure (2 torr) where the plasma is still not in local thermodynamic equilibrium. At low pressures the two temperatures are decoupled but as the pressure increases the temperatures tend towards the same limit. Читать дальше

Drift Diffusion Tutorial

The Drift Diffusion interface solves a pair of reaction/advection/diffusion equations, one for the electron density and the other for the mean electron energy. This tutorial example computes the electron number density and mean electron energy in a drift tube. Electrons are released ... Читать дальше
