Gasdynamic effects on an electric discharge in air
Abstract
The overall purpose of this work is to develop a subsonic,
turbulent, diffuse electric discharge operating at
near atmospheric pressure for use as the pumping mechanism
in an Electric Discharge Convection Laser (EDCL) . The
work was done in two phases. The first consisted of a
data collection phase during which the variation of discharge
parameters was studied to determine their effects
on the current-voltage characteristics of the multi-pin
electrode arrangements used. The parameters studied
included gap length, flow speed, turbulence intensity,
electrode orientation, rate of voltage increase, and gas
density through the addition of a diffuser. The second
phase consisted of developing an interactive model which
correctly reflects the dependences observed in phase one.
A space-charge model resulted which correctly explains
most major observed trends in gross discharge properties.
Discharge stability is also discussed in terms of the model.
