摘要：A 50-Hz rotating (annular-mode) gliding arc plasma in a vortex air flow is generated. Its dynamic evolution has been investigated through the electrical measurements and highspeed imaging, which shows that the arc is formed after several breakdowns of the gas and then glides stably with a low-discharge current. The intensity of the light emitting from the arc root at the cathode is remarkably higher than that at other areas during the arc gliding.
