Abstract
Transitional cold atmospheric plasma (TCAP) has emerged as a promising technology across various industries, such as medicine, food processing, materials, and other technological domains. In this experimental investigation, we explore the impact of transmission pipe length on TCAP characteristics, including voltage, current, and frequency, during the transmission process. To conduct this study, a dielectric barrier discharge (DBD) reactor served as the primary source for plasma transfer. TCAP plasma was generated using various gas combinations (argon, argon+nitrogen, argon+oxygen, and argon+air) within transmission tubes of varying lengths. The results revealed a direct correlation between transmission tube length and applied voltage, wherein an increase in tube length led to an increase in applied voltage and a decrease in electric current and plasma frequency. These observations stemmed from the relationship between tube length and the power required for plasma transfer. Furthermore, we observed distinct effects on plasma transport based on different gas compositions (argon, nitrogen, oxygen, and air), underscoring the influence of gas composition on TCAP plasma properties. Consequently, the plasma transfer process significantly impacts plasma-related parameters.
