Notes:
A one-dimensional continuum model for a dc-glow-discharge plasma between parallel-plate electrodes is presented, which is based on the local balance equations for particle densities and fluxes of electrons and ions, as well as on the local electron energy balance and the Poisson equation. In addition to similar treatments, the inertia term in the ion momentum balance equation leading to a singularity at the ion sound velocity, as well as the electron energy losses by excitation of atomic levels, have been taken into account. The system of nonlinear first-order differential equations supplemented by suitably chosen boundary conditions has been solved by the numerical procedure Henyey method ordinary differential equation solver, which allows also for the occurrence of removable singular points. Calculations for an argon plasma have been performed and the influence of parameter choices on the solution has been investigated. In general, the features typical for dc discharges are reproduced and agreement with the spatial profiles obtained by other authors with different methods is found.
