The Leibniz Institute for Plasma Science and Technology (INP) is the largest non-university institute in the field of low temperature plasmas, their basics and technical applications in Europe. The institute carries out research and development from idea to prototype. The topics focus on the needs of the market. At present, plasmas for materials and energy as well as for environment and health are the focus of interest.

Modelling of microarcs in copper metal vapour dominated air

Thermal Plasma Technology

The dataset contains results of a unified one-dimensional model of an arc plasma in air dominated by copper metal vapour. The plasma is generated between copper electrodes. The model resembles the microarcs that occur at low-voltage and low-current conditions in switching devices during a contact separation. Data concerning the plasma parameters, including electric potential, temperatures of electron and heavy particles, number densities of charged and neutral species are provided as tables.

Plasma Source Properties

DC electric arc between copper electrodes of 10 mm length in atmospheric-pressure air dominated by copper metal vapour. Inter-electrode distances of 30 µm and 300 µm are investigated at a constant current of 1 A.
Plasma Medium Name
air
Cu
Plasma Medium Properties

Air plasma dominated by Cu metal vapour. Evaporation from the electrodes is taken into account. The plasma chemistry involves 13 species (e, N2, O2, NO, N, O, N2+, O2+, NO+, N+, O+, Cu nad Cu+). It is assumed that the plasma behaves like a fluid, in which the heavy particles (neutrals and ions) are in thermal equilibrium at a common temperature T, while the electrons are characterized by a Maxwellian velocity distribution function with a temperature Te.
Plasma Diagnostics Name
fluid-Poisson model
unified fluid modelling
Plasma Diagnostics Properties

The governing equations include particle balance equations for electrons as well as all considered heavy species, heat balance equations for the gas and electrode temperatures, the electron energy balance equation and Poisson's equation for the electric potential.
