Penetration of gas discharge through the gas?liquid interface into the bulk volume of conductive aqueous solution

Popis výsledku v původním jazyce

Gas discharge plasma generated above the surface of conductive aqueous solutions in a glass capillary was used to study penetration of the discharge from the bubble (imitated by the space above meniscus of liquid surface in the capillary) into the bulk liquid. The experiments were conducted at both polarities with a high-voltage needle electrode placed above the liquid surface. Different aqueous solutions were examined (distilled water, conductive saline solutions). High-speed shadowgraphy was used as the main diagnostic tool for the study of the disturbances at the plasma-liquid interface. It has been found that electric field just beneath the liquid surface and the liquid/plasma conductivity ratio have a decisive effect on the development of plasma-liquid interface instabilities. Experiments with negative electrode above the liquid surface showed that this surface in the place of the largest current density recedes. This receding is caused by the reaction pressure resulting from
