“…Besides needs of the electric power industry, research of powerful arc of variable length and methods of its quenching has the great importance for the development of various technologies of lightning protection [7][8][9], plasma chemistry [10,11], aerodynamics [12,13] and others. The carrying out of experimental researches of the high current discharges at high pressure requires the creation of complicated testing systems [14].…”

The paper presents some results concerning electrophysical and gas-dynamics parameters of high-curent arc in axial blast discharge chamber. The experimental stand and numerical model were modified for axial gas flow type. Some design changes are described in the paper. The experiments were carried out for gas pressures of 1.0-6.0 MPa with current amplitude of 25-150 kA. The current half-period was of 1.0-10.0 ms. The contacts moved apart to the distance of 3-4 cm due to gas pressure boost in the chamber. OpenFOAM package with the library swak4foam was used for numerical simulation.
