Diagnosis of arc plasma jet flowing into air by integrating moiré and emission tomography

In this paper, moiré and emission tomography are integrated to visualize and diagnose the arc plasma jet flowing into air, and the argon arc plasma jet is chosen as a practical example for experiment. The refractive index distribution and structure of the measured flow field are simultaneously obtained by moiré and emission tomography respectively. As a result, the mixed flow field-arc plasma jet flowing into air can be divided into two regions. Finally, the different reconstruction models are adopted to obtain the temperature and electron number density distributions for the two different regions.
