Two-dimensional hybrid model for a glow discharge: comparison with fluid and kinetic (particle) models, reliability and accuracy

Rafatov, İsmail
We developed and tested a two-dimensional Monte Carlo – fluid hybrid numerical code for the DC glow discharge simulations. The model is based on the separation of electrons into two parts, namely, the low energetic (slow) and high energetic (fast) groups. Ions and slow electrons are described within the fluid model using the drift-diffusion approximation for particle fluxes. Electrostatic field is obtained from the solution of Poisson equation. Fast electrons, represented by the appropriate number of super particles emitted from the cathode, are responsible for ionization processes in the discharge volume. Test calculations were carried out for the argon plasma. The vortex current formation in a DC discharge is observed in the case of rectangular geometry.


Fluid model of dc glow discharge with nonlocal ionization source term
Rafatov, İsmail; KUDRYAVTSEV, A. A. (2012-06-29)
We developed and tested a simple hybrid model for a glow discharge, which incorporates nonlocal ionization by fast electrons into the fluid framework. Calculations have been performed for an argon gas. Comparison with the experimental data as well as with the hybrid (particle) and fluid modelling results demonstated good applicability of the proposed model.
Non-uniform axial electric field in argon glow discharge plasma
Akbar, D.; Bilikmen, S. (IOP Publishing, 2006-05-01)
The non-uniform argon dc glow discharge plasma system has been constructed in a very special design to investigate the effects of variable tube radius on plasma parameters. By using isolated computer controlled three couples of a double probe (TCDP) system, the electron temperature, electron density, the reduced electric field, and electron drift velocity are measured at low and intermediate pressures. It is shown that the electron temperature and reduced electric field (density) decreases (increases) as th...
