“…The estimation of numerical simulation results correctness is carried out by comparing experimental studies and simulation results. Verification of the mathematical model is carried out using experimental data on arc voltage and the methods of spectral diagnostics (for more information see [20][21][22][23]). Radial temperature distributions at different distances from the output of the plasma torch are obtained from the results of spectral diagnostics.…”

The article is dedicated to nonstationary simulation of DC air plasma torch. The mathematical model for the analysis of plasma jet instability is developed. The proposed 2D axisymmetric model demonstrates the physical processes taking place inside and in the outer region of the plasma torch. The influence of the power source parameters and anode geometry on voltage and plasma jet fluctuation is described. Simplified mathematical model is developed in order to assess the effect of the flow behavior on heat transfer processes. The developed model can be used for the design of plasma torches and their operation modes. The results of mathematical model verification are based on experimental studies.

The article deals with a high-voltage three-phase AC plasma torch working as a part of a plasma-chemical facility. The plasma torch consists of three electric arc channels and three rod copper electrodes. The initial breakdown occurs with high voltage (10 kV) provided by a high voltage power supply. The electric arc plasma oxygen-free pyrolysis of methane was realized on the facility. The fullerenecontaining fraction was extracted from the carbonaceous material by extraction with orthoxylene. The produced carbon-black and the selected extract were analyzed by modern methods of physical and chemical analysis: scanning electron microscopy, X-ray phase analysis, IR spectroscopy.
