Abstract

The ionization degree of the plasma in a nonstationary pulsating discharge created by a stationary power source in subsonic and supersonic airflows has been determined. lt was experimentally found that the electron density in the plasma near electrodes varies from 1015 to 3.7 × 1016 cm–3 and the gas temperature increases from 400 to 1250 K when the flow velocity varies from 150 to 520 m/s at a constant discharge current of 15.5 A. It is shown that the gas ionization degree in the pulsating discharge plasma is on the order of l0–4 at low subsonic airflow velocities, while with the increase in the flow rate it increases sharply and reaches the value of 10–2 at the velocity of 500 m/s.
