Numerical Simulation of Pulse-Periodic Nanosecond Electric Discharge in Air
摘要
Abstract
The results of the numerical simulation of a pulse-periodic nanosecond discharge are presented. An axisymmetric high-frequency (5 MHz) electric discharge in a pin-to-pin configuration is considered. Numerical models are used that take into account the chemical kinetics of high-temperature air and plasma chemistry, in which the reaction rates are determined by the magnitude of the reduced electric field. Preliminary results of plasma activation of atmospheric pressure air by a pulse-periodic nanosecond discharge are presented in order to intensify the production of chemically active particles (by the example of atomic oxygen).
