Аннотация:Nanosecond surface dielectric barrier discharge (nSDBD) is an efficient tool for a multi-point plasma-assisted ignition of combustible mixtures at elevated pressures. The discharge develops as a set of synchronously propagated from the high-voltage electrode charged channels (streamers), with a typical density up to a few streamers per millimeter of the length of the electrode. In combustible mixtures, nSDBD initiates numerous combustion waves propagating from the electrode. A very little is known about nSDBD at high pressures. This work presents a comparative experimental study of the surface dielectric barrier discharge initiated by high voltage pulses (U = ±(20 − 60) kV) of different polarities in air at elevated pressures (P =1 − 6 atm). Discharge morphology, deposited energy, velocity of the discharge front propagation are analyzed. Differences between the discharges of the different polarity, as well as the changes in the discharge morphology with changing
of a gas mixture composition, are discussed.
