Self-consistent fluid modeling and simulation on a pulsed microwave atmospheric-pressure argon plasma jet

摘要: In present study, a pulsed lower-power microwave-driven atmospheric-pressure argon plasma jet has been introduced with the type of coaxial transmission line resonator. The plume is room air temperature, even can be directly touched by human body without any hot harm. order to study ionization process proposed jet, self-consistent hybrid fluid model constructed in which Maxwell's equations are solved numerically finite-difference time-domain method and used characteristics evolution. With Guass input power function, spatio-temporal distributions electron density, electric field, absorbed density have simulated, respectively. simulation results suggest that peak values temperature field synchronous microwave but maximum quantities lagged excitation. addition, excited local enhanced surface plasmon polaritons should discharge mechanism jet.
