The arc discharge was studied in a transparent channel at an intense flow rate of nitrogen, hydrogen, air, carbon dioxide in the current range 100–1500 A. The internal diameter of the porous channel varied from 10 to 34 mm, the length ‐ from 50 to 150 mm, the air and nitrogen flow rates ‐ from 0.05 to 1.5 kg/s, hydrogen ‐ from 0.005 to 0.05 kg/s. The electric field strength in the arc channel reached a value of 300 V/cm for N 2 and 500 V/cm for H 2 . The effect of plasma thermochemical non‐equilibrium was discovered.
