posted on 2009-08-28, 10:13 authored by Felipe IzaFelipe Iza, James L. Walsh, Michael G. KongWe have developed a time-hybrid computational
model to study pulsed atmospheric-pressure discharges and compared
simulation results with experimental data. Experimental
and computational results indicate that increasing the applied
voltage results in faster ignition of the discharge and an increase
in the mean electron energy, opening the door to tunable plasma
chemistry by means of pulse shaping. Above a critical electric field
of ~2 kV/mmfor ~1-mm discharges, pulsed plasmas ignite right
after the application of an externally applied voltage pulse. Despite
the large pd value (30–300 torr · cm) and the high applied electric
field, the discharges are found to be streamer free in a desirable
glowlike mode. The comparison of the time evolution of the mean
electron kinetic energy as a function of the pulse rise time suggests
that a fast rise time is not necessarily the best way of achieving
high mean electron energy.
