A single channel discharge reactor for the diagnosis of dielectric barrier discharge reactors

A single channel discharge reactor (SCDR) has been developed for the diagnosis of DBD reactors. The SCDR consists of two alumina plates and two stainless steel rod electrodes. The single discharge channel can be fixed in the space between two alumina plates covered with the stainless steel rod electrodes. The discharge generated by a pulse power supply is characterized using a monochromator equipped with an ultra high-speed streak camera to measure light emission at various discharge times, and an oscilloscope with a voltage probe and two current transformers to monitor waveforms of discharge voltage and currents, respectively. The energy density, total charges, electron density, size of discharge channel, vibrational temperature, and gas temperature are calculated. A comparison of SCDR with a DBD reactor of many filamentary discharge channels is given.
