Abstract
In this work, we carried out two-dimensional numerical simulation of atmospheric pressure dc glow discharge with miniature helium flow in nitrogen. The glow discharge is generated along the helium flow, which is injected from the nozzle anode into the discharge region filled with nitrogen. The purpose of this study is to clarify the relationship between the glow discharge structure and the helium flow. We found that the glow discharge generation is limited in the region with a very high helium mole fraction. Therefore, the helium mole fraction is an important parameter to determine the discharge structure along the helium flow.
