Abstract

Physico-chemical model, numerical methods and computation results for equilibrium inductive coupled plasma flows in plasmatron are presented for the five gases: air, nitrogen, oxygen, argon and carbon dioxide. Corresponding database includes thermodynamic and transport properties of the gases at temperature range 300 − 15000 K. Effective technique for calculation of multicomponent ionized gases transport properties is used based on the new formulation of Chapman-Enskog method with account for high approximations by Sonine polynomials. Some results of inductive plasma flows modeling at pressure 0.1 atm are presented. Numerical solutions of the Navier-Stokes equations coupled with quasi-ID approximation of Maxwell equations for stationary laminar axisymmetric flows with swirling have been obtained by Patankar-Spalding method. Some results have been obtained also by a new effective preconditioning technique and implicit finite difference scheme for solving the Navier-Stokes equations in the Mach number range 0,01 < M < 1.
