Originální abstrakt
Electrical discharges in liquids can be generated in several electrode configurations; one of them is called as pin-hole. The discharge is created inside a small orifice in the dielectric barrier connecting two chambers filled by any conductive solution. Each chamber contains one electrode. Based on the orifice length/diameter ratio, the discharge is called as capillary or diaphragm. The present paper gives the first detailed observation of the dependence of discharge creation on the orifice shape for selected NaCl solution conductivities (250-1000 microS/cm). As a dielectric barrier, ceramic discs with thickness varying from 0.3 to 1.5 mm were used. Diameter of one central pin-hole was in the range of 0.25-1.00 mm. The non-pulsing DC high voltage up to 2 kV with power up to 300 W was used for the presented study. The bubble theory of the discharge generation was confirmed at the set conditions.
