Descripción
The glow-to-arc transition of a convection-stabilized atmospheric pressure air discharge is numerically investigated. Two separate models are considered: a one-dimensional axisym metric time-dependent fuid model of the positive column, describing the thermal-instabil ity, and a sheath model of a cold cathode describing the feld-emission instability, which must then be properly matched together. The fuid model considers the most important chemical reactions in air plasma, including thermal ionization in atomic collisions. The radial electric feld in the plasma is obtained from the Poisson equation. The voltage–cur rent characteristic of the discharge is simulated for a time-varying current up to 300 mA. It is found that at some critical value slightly above 200 mA, the contraction of the positive column arises from a vibrational–translational energy relaxation. The subsequent increases in the discharge current density in the positive column drive in turn a feld-emission insta bility in the cathode, which is accompanied by a large voltage drop. Simulation results are validated against available experimental data.
