Nanosecond Pulsed Plasma Discharge in High-speed Flow

This study explores the characteristics and behavior of Nanosecond Pulsed High-Frequency Discharge (NPHFD) plasma within high-speed airflow environments. Utilizing a detailed experimental setup including high frame-rate schlieren and high-speed infrared imaging systems, The study examined the effects of varying electrode gap distances and airflow velocities on plasma discharge elongation. Our results demonstrate a significant dependence of plasma discharge behavior on the inter-electrode gap distance and airflow velocity. These findings provide insights into the optimization of plasma-assisted ignition processes in high-speed flows, crucial for the development of efficient aerospace combustion systems.
