Exploring Flow Field Dynamics for Improved Volatile Organic Compound Conversion in Surface Dielectric Barrier Discharge Systems*

Volatile organic compounds (VOCs) pose risks to both the environment and human health and are challenging to remove energy-efficiently. As a novel alternative to conventional systems, surface dielectric barrier discharge systems show great potential for VOC degradation. In this study, we investigate the role of discharge-induced flow field structures in conversion processes. Focusing on n-butane as a benchmark molecule, we employ flame ionization detectors to monitor conversion and planar particle image velocimetry to analyze flow dynamics. Varying the gap distance between SDBD electrode plates reveals a correlation between discharge-induced fluid dynamics and conversion. Our findings bridging plasma actuator research with chemical plasma gas conversion and present new possibilities for system optimization.
