基于双进气结构的微波大气压空气冷等离子体性质调控研究
Study on Property Regulation of Microwave Atmospheric-pressure Air Cold Plasma Based on a Dual-inlet Structure
摘要
Abstract
For the proposed atmospheric-pressure air cold plasma source with dual-inlet structure,the effects of the dual-inlet structure on discharge morphology and concentrations of reactive species(NO and O3)under dif-ferent experimental conditions are investigated.The results demonstrate that the dual-inlet structure can effectively regulate the plasma plume length,and enhance the concentrations of NO and O3 within an appropriate flow rate range.The maximum concentrations of NO and O3 can reach 250 ppm and 20 ppm,respectively,which highlights the significant advantages of the dual-inlet structure in controlling reactive species.By using argon as the auxiliary gas allows for an extended plasma plume while maintaining reactive species concentrations and reducing plasma temperature,thereby improving its suitability for biomedical applications.The research provides valuable insights for plasma"dosage"optimization and precise applications in medicine.关键词
