Abstract
Unified jet-DBD design, JDBD, proposed in this work presents large-scale plasma in an unbounded region of atmospheric air, without any need for the flow of gas, offering efficient exposure to sizable and complex objects. This is a simulation-based architecture for stable non-thermal plasma source with notable experimental results. JDBD geometry optimizes the electric field and charge distribution for a diffuse discharge in the steady air by a key design parameter of efficient insulation. Teflon insulator with a thickness d(Tf) >= 10 mm imposes an intense and uniform electric field shaped up at the open area in front of the device and generates radially/axially expanded plasma jet. In the JDBD, phase shift increases by I-rms and the plasma generates more power than the classical plasma jet. Two distinct states of JDBD operation indicate the mode-swap at 0.8 mA and power dissipation. In the reactive JDBD scheme even small changes in the phase angle effectively improves the electric power.
