“…For various practical and technological problems, it is necessary to know the distributions of electrical and thermal parameters of a given type of discharge [2][3][4][5][6][7][8][9][10][11][12]. Knowledge of the physics of the processes of interaction of the discharge with the gas flow, the instabilities arising in it, will allow controlling the discharge parameters for various technological operations [13][14][15][16][17]. Therefore, the study and research of GD plasma parameters is of great scientific and practical interest [18][19][20][21].…”

The article is devoted to an experimental study of transient processes in a glow discharge (GD). The longitudinal GD was ignited in a stream of air in a cylindrical discharge chamber (DC). Copper hollow electrodes were located at a distance of a = (2 -8) cm from each other along the axis of the DC. The gas pressure P, its flow rate G, discharge current I and its voltage U varied accordingly in the ranges: P = (4.7 -26) kPa, G = (0 -0.05) g / s, I = (20 -100) mA, U = (1. 5 -4. 2) kV. The current-voltage characteristics of the discharge were measured. The voltage decreased with increasing current, which is typical for a given type of discharge. The oscillations of the discharge voltage were registered by an oscilloscope; the current-voltage characteristic of the discharge was recorded by a two-coordinate recorder. Low-frequency (f ~ 300 Hz) and high-frequency (f ~ 100 kHz) oscillations of the discharge voltage were observed. The influence of the gas flow on the current-voltage characteristics of the discharge, its shape and the frequency of the detected oscillations is shown.
