The results of modelling study of self-pulsing discharges in pure argon at atmospheric pressure in a 1.5 mm gas gap are provided in this dataset. The study investigates the interaction between the electrical circuit and the actual plasma characteristics. A time-dependent, spatially one-dimensional fluid-Poisson model coupled with an equivalent circuit equation is applied to analyse the impact of circuit parameters like resistance and applied negative DC high voltage on basic discharge properties.

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.

The dataset contains the data presented in the paper introducing the FEDM (Finite Element Discharge Modelling) code. The FEDM code was developed using the open-source computing platform FEniCS (https://fenicsproject.org). Building on FEniCS, the FEDM code utilises the finite element method to solve partial differential equations. It extends FEniCS with features that allow the automated implementation and numerical solution of fully-coupled fluid-Poisson models, including an arbitrary number of particle balance equations.
