This research investigates arc dynamics and CO2 conversion in an AC-driven reactor, implying improved efficiency with better flow design.
The AC‐driven rotating gliding arc (AC‐RGA) reactor offers advantages in simplifying discharge systems and reducing energy losses. Using CO 2 as the working gas, this study examines how gas flow rate and inlet configuration influence arc dynamics, electrical behavior, and CO 2 conversion. Compared with the single‐inlet design, the four‐inlet configuration generates a more uniform flow field, stabilizing arc rotation, reducing voltage fluctuations, and enhancing CO 2 conversion and energy efficiency. Optical emission spectroscopy and exhaust temperature analyses indicate that the uniform flow suppresses CO and O recombination while promoting CO 2 + formation, thereby improving decomposition efficiency and highlighting the importance of flow uniformity in optimizing AC‐RGA performance.
