Thermal study on DBD reactor with intermediate frequency voltage

Temperature in Dielectric barrier discharge (DBD) reactor increased obviously under high frequency alternating current (AC). The change trends of DBD temperature were tested. Heat transfer mechanism was established, and formula of energy distribution and ΔT_ave were educed. The experimental results show that DBD temperature increased with voltage and time increasing in high frequency discharge and their relationships were non-linear. DBD temperature increased with frequency and time increasing, and with gas influent rate decreasing. All of these factors and DBD temperature presented linearity. At the end, there was a better foreground for application to industry or family of low frequency AC in the future.
