Repetitive Nanosecond Volume Diffuse Discharge Under Airflows

This paper illustrates a repetitive nanosecond volume discharge in the airflows at different velocities. The plasma images presented here show that the volume discharge modes vary with the changes of airflow speeds, and a diffuse and homogeneous volume discharge occurs at the airflow speed of 30 m/s. The discharge is promoted in the airflows at a lower velocity, and the discharge tends to be inhibited at a speed to 40 m/s. However, the inhibited mode disappears at higher repetitive frequency of the pulse.
