Dielectric Barrier Discharge
Model ID: 8637
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 highlight the physics of the breakdown process, the model uses a simple argon chemistry, which keeps the number of species and reactions to a minimum.
|DIELECTRIC BARRIER DISCHARGE: A small gap is filled with a gas between two dielectric plates. Voltage is applied so that any free electrons will be accelerated and cause ionization. Shown is the mass fraction of electronically excited Argon atoms.|
