Abstract

In this study, we conducted a series of numerical experiments, which two modes of corona discharge in argon at atmospheric pressure were reproduced: pulse periodic and glow. The results demonstrated that with an increase in the power deposited in the discharge, the oscillation frequency increases, and the amplitude decreases. When the threshold current is reached, the corona discharge goes into glow mode. Since the corona discharge is characterized by a high electric field near the tip, considerable heating is observed in this region of the interelectrode gap even at low currents at atmospheric pressure. In this regard, a falling current-voltage characteristic of the discharge is observed.
