Abstract

Two types of electrical discharges in atmospheric pressure air plasmas are investigated. The first discharge investigated, a positive DC corona operating in ambient air, is used to accelerate an air flow using the ion wind effect. The flow velocity profile is measured by Laser Doppler Velocimetry (LDV) and is compared with the results of a simplified model. In the second part of this paper, we give a brief progress report of our studies of high voltage nanosecond discharges repetitively pulsed at frequencies of up to 30 kHz. These discharges are applied to atmospheric pressure air at temperatures in the range 300-1000 K, in order to determine the recombination of electrons as a function of the gas temperature.
