Abstract

The pulsed corona discharge in water produces radicals and reactive species, such as O, OH and H₂O₂, which can oxidize organic compounds to H₂O and CO₂. However, the pulsed corona discharge in water generates also shock waves and numerous bubbles, which contains water, vapour, oxygen, hydrogen and active species. In this work results of the laser visualization of the gas bubbles flow in a needle-to-cylinder pulsed corona discharge reactor filled with distilled water are presented.
