The aim of this paper is to study the effects of the magnitude
and direction of air flow rate on the characteristics of the corona
discharge generated in a wire-duct reactor. Two air flow directions were
attempted: one parallel to, and the other normal to the discharge wire in
the reactor. The corona current-voltage characteristics correlative with
ozone generation were studied under different modes of applied voltage.
The results have shown that dc and ac corona current-voltage
characteristics depend significantly on the magnitude of the air flow rate
in the reactor, whatever the direction of the air flow. The ozone
concentration generated by either dc, ac or pulsed coronas with parallel
flow is higher than that generated with normal flow with the same
discharge conditions. The ozone concentration generated by pulsed coronas
is higher than that generated by either dc or ac coronas with the same
discharge conditions irrespective of the polarity of the pulsed corona.
