High voltage AC plasma torch: dynamics of plasma-forming gas

A mathematical model of the multiphysical processes occurring in an alternating current plasma torch has been developed. A numerical study of the dynamics of plasma-forming gas (air) for a single-phase plasma torch developed at the IEE RAS operating at atmospheric pressure has been carried out. The calculation results are compared with experimental data The proposed model and computational algorithm can be used to estimate gas parameters in plasma torch channels and the reactor area when developing modern technologies for the synthesis/destruction of materials.
