摘要
This work is devoted to the experimental investigation of an AC argon gliding arc discharge at atmospheric pressure.The dynamic behaviour of the argon gliding arc plasma is investigated by the oscillations of the electrical signals,while the time-resolved arc root motion behaviour on the electrode wall is analyzed by high-speed photography.It is found that the anode and cathode arc roots exhibit different motion behaviour on the electrode surface.In addition,emission spectroscopic technique has been employed to determine the axial distribution of the gas temperature and electron density in the argon gliding arc plasma.
This work is devoted to the experimental investigation of an AC argon gliding arc discharge at atmospheric pressure. The dy- namic behaviour of the argon gliding arc plasma is investigated by the oscillations of the electrical signals, while the time-resolved arc root motion behaviour on the electrode wall is analyzed by high-speed photography. It is found that the anode and cathode arc roots exhibit dif- ferent motion behaviour on the electrode surface. In addition, emission spectroscopic technique has been employed to determine the axial distribution of the gas temperature and electron density in the argon gliding arc plasma.
