Abstract
International audience; In atmospheric pressure air preheated from 300 to 1000 K, the nanosecond repetitively pulsed (NRP) method has been used to generate corona, glow, and spark discharges. Experiments have been performed to determine the parameter space (applied voltage, pulse repetition frequency, ambient gas temperature, and interelectrode gap distance) of each discharge regime. In particular, the experimental conditions necessary for the glow regime of NRP discharges have been determined, with the notable result that there exists a minimum and maximum gap distance for its existence at a given ambient gas temperature. The minimum gap distance increases with...

V − 0 = 0. Because d is small compared to the distance between the electrodes and other conducting surfaces at V = 0 in our experiments, symmetry is nearly preserved, with V 0 Vp / 2 and E z −E −z . To account for V 0 = Vp, V 0 Vp / 2, and V − 0 = 0, we divide the right side of Eq. B2 by two to yield Eq. 1 for the Laplacian electric field in our pin-pin electrode configuration.
