ABSTRACT
The computing model of quasineutral gas discharge plasma in a magnetic field is developed and applied to predict a viscous-inviscid interaction in a hypersonic boundary layer. Numerical simulations are performed for a range of magnetic field flux densities (B=0.1−1 tesla) imposed transversely to gas flow. The numerical result demonstrates a strong influence of the magnetic field to electrodynamic and gas-dynamic structures of weakly ionized gas flow.

Keywords:  Quasi-neutral plasma; Viscous-inviscid interaction; Hypersonic boundary layer
