Verification and analysis of flowing gas discharge – Part II

Using an artificial wind tunnel, the three basic preconditions presented in the preceding article by Kang et al are experimentally verified and systematically analyzed. The experimental results confirm that, in a discharge of flowing air, the breakdown path of an air gap deflects at an angle along the direction of the airflow. Some of electrons and ions are blown away by the airflow, and the mean free path of electron increases with increasing airflow velocity. In addition, the physical essences of the effects of flowing air on the discharge are revealed, and the differences in flowing air discharge between the uniform and non-uniform electric fields are discussed.
