The paper presents computational studies of working medium dynamics in a coaxial accelerator used in the surface engineering for impulse plasma deposition (IPD). Plasma discharge has been investigated with a two-dimensional mono-fluidic snow plow model and a two-dimensional two-fluid magnetohydrodynamic code. Numerical simulations have significantly increased the understanding of phenomena during...
The paper discusses the mechanism of the generation and spreading of an impulse plasma in a coaxial plasma accelerator. An accelerator of this type utilizes the electrodynamic mechanism of ion acceleration. The existing descriptions of the plasma spreading in a coaxial accelerator are based on the @'snow plough@' model. This model is not suitable for describing the behaviour of impulse plasma during...
