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.

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 column. The discharge is sustained by emission of secondary electrons at the cathode.

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.

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 problem is reduced to 1D by assuming the dielectric gap is much smaller than the diameter of the plates. To ...

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 due to thermionic emission on the left boundary with an assumed mean electron energy. The electrons are then ...

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. This model investigates the electrical characteristics of the GEC reference cell for argon chemistry.

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 partially absorbed and reflected by the plasma which sustains the plasma.

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 process chamber from two 2 inch ports and the gas is extracted through a single 4 inch port. The plasma is ...

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.

Benchmark Model of a Capacitively Coupled Plasma

The underlying physics of a capacitively coupled plasma is rather complicated, even for rather simple geometric configurations and plasma chemistries. This model benchmarks the Capacitively Coupled Plasma physics interface against many different codes.
