Generation of Audio Frequency Pin-Hole Discharge in Water Solutions

Popis výsledku v původním jazyce

This paper presents results on electric discharge generation by high frequency high voltage (15-100 kHz) in NaCl solutions with different initial conductivity (100-1300 microS/cm), and compares them with DC discharge in the same electrode configuration.A batch plasma reactor in the pin-hole configuration contained a ceramic dielectric barrier separating two planar stainless steel electrodes; barrier thickness of 0.6 mm and pin-hole diameter of 0.6 mm was used. Lissajouse charts were evaluated from electric measurements for different discharge phases (electrolysis, bubble formation and discharge regular operation). Breakdown moments for different solution conductivities were determined from discharge power evaluation as a function of applied frequency.Breakdown voltage amplitude was decreased by the increasing conductivity in both regimes while frequency and current decreased. Changes of physical parameters (temperature, solution conductivity and pH) as well as production of hydrogen
