Abstract
Subsonic equilibrium air and argon plasma flows in the cylindrical discharge channel of an induction plasmatron are calculated over a wide range of the working parameters on the basis of a solution of the complete Navier-Stokes equations combined with a simplified equation for the high-frequency electric field. An effective method and the results of calculating the necessary transport coefficients of ionized multicomponent air and argon (including the plasma electrical conductivity) are given on the temperature interval 300–1500 K with allowance for the higher approximations in Sonine polynomials in the Chapman-Enskog method. The results of calculating the air and argon plasma flow and temperature field in the discharge channel of a 100 kW induction plasmatron are given. Two types of complex channel plasma flow vortex structures are detected.
