Atmospheric pressure non-thermal plasmas are now being used for various applications such as pollution control, light sources, medical and waste. Here a self-consistent continuum model is presented for a narrow gap plane-parallel dc glow discharge. The set of governing equations consisting of continuity and momentum equations for positive ions, fast ( emitted by the cathode) and slow electrons (generated by fast electron impact ionization) coupled with Poisson's equation is treated by the technique of matched asymptotic expansions. This analytic procedure reduces the unnecessary computational effort associated with Monte-Carlo approach with acceptable accuracy. In addition, it is more physically transparent.
