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 ... En Savoir Plus

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 ... En Savoir Plus

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 ...

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. En Savoir Plus

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. En Savoir Plus

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 ... En Savoir Plus

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 ... En Savoir Plus

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. ... En Savoir Plus

Thermoelectric generator

In this model, we show how to model Seebeck effect which works as a thermoelectric generator. Seebeck effect is a phenomena where the difference in temperature of a material leads to a potential difference. The potential drawn in this model was compared with the paper by Jaegle (Example ...

Dipolar Microwave Plasma Source

This model presents a 2D axisymmetric dipolar microwave plasma source sustained through resonant heating of the electrons. This is known as electron cyclotron resonance (ECR), which occurs when a suitable high magnetic flux density is present along with the microwaves. This is an ... En Savoir Plus
