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

ORAL

Abstract

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.
