Abstract

The paper considers the results of experimental and computational efforts on study of the filamentary transversal pulse discharge dynamics in high-speed airflow. The effect of fast turbulent expansion of the post-discharge channel is studied experimentally in order to enhance mixing processes of fuel and oxidizer and reduce the time of ignition. It is shown experimentally that the pulse-repetitive discharge disturbs the flown gas significantly if the time period between individual pulses is about d/V, where d = inter-electrode gap, V= flow velocity. The phenomenon of the discharge localization near boundary of two gases is demonstrated experimentally; the physical mechanism is discussed.
