Dielectric barrier discharge in argon appears under normal circumstances in form of microdischarges. Addition of some gasses i.e. ammonia can lead to transition to diffused barrier discharge. Explanation for such behavior can be obtained by numerical simulation. For development of model detailed knowledge of main processes in dielectric barrier discharge in argon are required.

This contribution gives basic comparison between experiment and numerical simulation of dielectric barrier discharge in argon. Simple 1D fluid model was developed for numerical simulation. The model uses Piecewise Parabolic Method for continuity equation solution. Calculations are performed on simple homogeneous spatial mesh with adaptive time step. Experimental data consist of electrical measurement and time and spatially resolved optical emission spectroscopy. Goal is to determinate basic processes in argon discharge. Obtained results will later be used in simulation of mixtures of ammonia with argon.
