Laser visualization of the flow of bubbles in a pulsed streamer discharge in water

The pulsed corona discharge in water produces radicals and reactive species, such as O, OH and H202, which can oxidize organic compounds to H20 and CO2. However, the pulsed corona discharge in water generates also shock waves and numerous bubbles, which contains water vapor, 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.
