Volatile organic compounds (VOCs) pose a significant risk to the environment and human health, and their energy-efficient removal remains a challenge. Surface dielectric barrier discharge (SDBD) systems have emerged as a promising alternative to conventional methods for VOC degradation. In this study, we introduce novel multi-electrode SDBD reactors designed to analyze induced flow field structures and their influence on conversion efficiency. Our findings reveal a correlation between induced flow dynamics and plasma-driven gas conversion, linking plasma actuator research with chemical plasma gas conversion.
The n-butane conversion was monitored with flame ionization detectors alongside planar particle image velocimetry to study the induced fluid dynamics. By varying the gap distance between SDBD plates, we identified localized peaks in relative conversion, indicating spatially dependent effects. The flow field analysis reveals distinct vortex structures forming on both SDBD sides, which change in size and shape as the gap distance increases. Further examination of vorticity and turbulent kinetic energy provides deeper insights into these vortex structures, highlighting the important role of fluid dynamics by enhanced gas mixing in the gas conversion process.
