Low direct current arcs generated between Cu electrodes in atmospheric pressure air are investigated in relation to low-voltage switching. Electrical and optical measurements and high-speed imaging give insight into the dynamics of the arc. Side-...
The data correspond to the results of modelling studies of DC electric arcs at a current of 2 A in air with admixture of copper metal vapour. Experimental findings are used to adjust input parametrs of the model in order to achieve a good match....
The dataset provides the data related to the modelling of microdischarges in metal vapour of cadmium. Such microdischarges occur in a testing equipment for the safety assessment of electric devices for explosion protection. A one-dimensional...
A pre-study of free burning arcs between carbon electrodes for potential use in gasification processes is presented. Free-burning arcs offer the potential to be used without additional gas feed or significant changes to gas flows in established...
This dataset contains plasma parameters of microarcs generated between a cooled copper anode and a ceriated tungsten cathode by means of a one-dimensional unified non-equilibrium model for gap lengths between 15 and 200 µm and current densities...
This plasma source is a commercial welding power source produced by Miller Electric Manufacturing Co., Appleton / USA. This welding system is precise, digitally controlled and software-driven. Several different wire feeding and operator interface...
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-...
The radiative heat transfer in arc plasma models is considered from the point of view of its description in terms of a net emission coefficient, the method of spherical harmonics in its lowest order, and the discrete ordinate method. Net emission...
The dataset contains results of a unified one-dimensional model of an arc plasma in air, between copper electrodes, that includes the change of the gap distance. The occurance of multiple reversals of the electric field and the anode voltage drop...
Double-pulse laser induced breakdown spectroscopy (LIBS) measurements in water with up to 600 bar hydrostatic pressure and 150 mJ energy of each pulse were done to select a setup which promote separated spectral lines in the observed plasma...
