Abstract

The AC-driven rotating gliding arc (AC-RGA) reactor offers advantages in simplifying discharge systems and reducing energy losses. Using CO₂ as the working gas, this study examines how gas flow rate and inlet configuration influence arc dynamics, electrical behavior, and CO₂ 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 CO₂ conversion and energy efficiency. Optical emission spectroscopy and exhaust temperature analyses indicate that the uniform flow suppresses CO and O recombination while promoting CO₂⁺ formation, thereby improving decomposition efficiency and highlighting the importance of flow uniformity in optimizing AC-RGA performance.
