Аннотация:Multi-parameter study on the subsonic equilibrium air plasma flows in the cylindrical dischargechannel of an induction RF-plasmatron IPG-3 with the maximum operating power of 1MW is presented. Simulations are carried out by numerical solution of full Navier–Stokes equations coupled with a two-dimensional equation for high-frequency electric field. Simulation results are presented, including the flow fields, electric field, and thermodynamic parameters of the air plasma in the discharge channel of a high-power induction plasmatron. The results obtained reveal for the first time the structure and parameters of a plasma torch in a large-diameter (200mm) discharge channel at powers up to 300kW, providing the axial specific enthalpies at the channel outlet as high as 68 MJ/kg.
