Abstract

A non-thermal arc plasma generator was developed with three-electrode configuration. With the help of the surface dielectric barrier discharge (DBD) produced between the main electrode and floating electrode, the ignition voltage of the non-thermal arc discharge was reduced, and a steady state non-thermal arc plasma was obtained. Experiments show that the temperature of the non-thermal arc generated using this three-electrode plasma generator is 2.0×10³-3.0×10³K and that there exist three different operating modes, i.e., the non-thermal arc mode, the non-thermal arc-DBD hybrid mode, and the surface DBD mode, with the increase of the plasma working gas flow rate while keeping other parameters unchanged. The results also show that increasing the power input at a constant gas flow rate benefits maintaining a non-thermal arc discharge mode. The developed non-thermal arc plasma generator is useful for producing non-thermal arc plasmas at low applied voltages, and for maintaining non-thermal arc discharges at high gas flow rates.
