Functional enhancement of a non-equilibrium plasma jet by seeding in the applied magnetic field

The experimental study is conducted to clarify the functional enhancement of a non-equilibrium argon plasma jet by seeding potassium in the applied magnetic field to extend its industrial applications. It is shown that the plasma parameters such as electron number density and electron temperature increase considerably by seeding especially in the applied magnetic field, which results in the easy enhancement of transport properties such as electrical conductivity and electron thermal conductivity. Finally, the infrared thermography is shown to visualize the relative variation of radiative temperature field comparing both with seeding and without seeding.
