Simulation of 1D atmospheric pressure dielectric barrier discharge in argon

Abstract

This work aims at modelling an atmospheric-pressure homogeneous
barrier discharge in argon, using a time-dependent 1D fluid model coupled to the
electric field and plasmo-chemical kinetic equations. The model is chosen to mimic a
discharge when a sinusoidal 1kV voltage at 10MHz is applied to the terminals. Energy and mass transfer are considered for a macroscopic fluid representation, while energy transfer in molecular collisions and chemical reactions is treated at the microscopic
level. The macroscopic model is represented by a set of uncoupled partial differential equations. Microscopic effects are studied within a discrete model for electronic and molecular collisions in the frame of ZDPlasKin, a plasma modelling numerical tool. The BOLSIG+ solver is employed in solving the electronic Boltzmann equation. An operator splitting technique is used to separate microscopic and macroscopic models. The spatial and temporal evolution of such species and electron transport parameters are presented and discussed.
