The results of the modelling of a filamentary dielectric barrier discharge (DBD) in argon at atmospheric pressure obtained using a time-dependent and spatially two-dimensional fluid-Poisson model in axisymmetric geometry are provided in this dataset. The model was employed to investigate the formation mechanisms of the striations along the discharge channel in a one-sided DBD arrangement with a 1.5 mm gap powered by a sinusoidal high voltage applied at the metal electrode.

Modelling results obtained using an extended reaction kinetics model (RKM) suitable for the analysis of weakly ionised, non-thermal argon plasmas with gas temperatures around 300K at sub-atmospheric and atmospheric pressures are presented. Modelling was performed by means of a time- and space-dependent fluid model for two different dielectric barrier discharge configurations as well as for a micro-scaled atmospheric-pressure plasma jet setup. The results are also compared with measurements, as well as with modelling data obtained by use of a previously established 15-species RKM.
