CALCULATION OF AIR GLOW-DISCHARGE SPATIAL STRUCTURE

Results of probe electric-potential measurements in a glow discharge i n air flow are presented. A simplified four-component scheme for solvi ng a spatially nonuniform problem was developed, based on the detailed analysis of plasmochemical processes in dry air glow discharge at nea r-atmospheric pressure. The computation data was compared with the res ults of probe measurements of the electric potential distribution with in a discharge gap. The results of electric current density measuremen ts were also analyzed. A reasonable agreement of the computer data and experimental results was found in most parts of the discharge volume.
