Discussion on the Non-Equilibrium Phase of the Gliding Arc Plasma Driven by the Transverse Magnetic Field

Abstract

A gliding arc driven by the transverse magnetic field was ignitedbetween the electrodes with a complicated shape at atmosphericpressure and a non-equilibrium plasma was generated. Under ourexperimental conditions, a phenomenon was clearly observed where thearc power decreased with the increase in arc voltage. As the arcvoltage was higher than 3.375 kV, the arc power acquired from thepower supply decreased, and the arc plasma began to switch to anon-equilibrium phase. The existence of the non-equilibrium arcplasma was very short, about 10 ms in one gliding arc dischargecycle.
