Streamer-surface interaction in an atmospheric pressure dielectric barrier discharge in argon - datasetThe results of the modelling of an atmospheric-pressure dielectric barrier discharge (DBD) in argon obtained using a time-dependent and spatially two-dimensional fluid-Poisson model in axisymmetric geometry are provided in this dataset. The spatiotemporal evolution of the electron number density, electric current, applied, memory and gap voltage, the spatial distribution of the number density of electrons and argon excited atoms, the electric field, electron production and loss rates, and surface charge density distribution are used for the analysis of the surface-streamer interaction and the cathode-layer formation. The analyses showed that the radial deflection of the volume streamer is driven by the free electrons that remained in the volume from the Townsend pre-phase and guided by the radial component of the electric field. The surface discharge, occurring simultaneously with the propagation of the deflected volume streamer, is governed by ion-induced secondary electron emission and the surface charges accumulated on the dielectric.

Due to their size, the data are saved in binary hdf5 file. The file can be opened using any program that supports opening hdf5 files, such as HDF Viewer, Origin Pro, Matlab, or various libraries in python. The data are stored as a three-column form table in which for a given time in the first column all axial positions are varied in the second column, whereas the third column contains the number density of electrons at the given time and position.
