Venturi-DBD

Extended reaction kinetics model for non-thermal argon plasmas and its test against experimental data - Dataset

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.

The gas pressure is an effective parameter to control plasma-chemical reactions, but its adjustment often requires substantial effort. In the Venturi-DBD (VDBD), the pressure can be set to any value between 100 mbar and 1000 mbar reliably and reproducibly. Using a Venturi pump for vacuum generation ensures that the system is affordable and almost maintenance-free. With air as process gas, the output gas composition can seamlessly be adjusted from a strongly ozone-dominated regime to a nitrogen oxides-only-regime including nitric oxide.

Influence of surface parameters on dielectric-barrier discharges in argon at subatmospheric pressure - dataset

The provided data describe the discharge current in DBD obtained by fluid modelling using different values of for the secondary electron emission coefficient γ and and the relative permittivity of the dielectric barrier εr in comparison with the measured current at a pressure of 100 mbar and an applied voltage amplitude of 1.8 kV. Furthermore, the dissipated power obtained by model calculations for different values of γ and εr together with the measured power in dependence on the pressure is given.
