abstract |
A non-equilibrium electrical discharge, driven at 325 kHz in atmospheric pressure
ambient air can be used as an acoustic source. Electrical and optical data for the
unmodulated, free-burning, vertical arc discharge are compared with a fluid model
based on the dominant collision processes in nitrogen –oxygen mixtures. For a 15 mm
long, 20 mA discharge, observations and the model reveal that the gas temperature
is ~3000 K, the axial field is ~100 kV m-1 and the electron density is ~ 2 1017
m–3; the column radius is ~1 mm in terms of optical emission, but the gas temperature
width is about three times broader |
