Sažetak

U radu se razmatraju rezultati numeričke simulacije brzog pražnjenja pri atmosferskom pritisku u visoko nehomogenoj konfiguraciji diode tipa vrh-ravan napunjene smešom azota i kiseonika. Simulacija se zasniva na savremenom hidrodinamičkom modelu pražnjenja plazme, koji takođe uzima u obzir fotojonizaciju gasa. Pokazano je da se, u odsustvu fotojonizujućeg pražnjenja, on razvija slično kao i kod fotojonizacije, sa izuzetkom napona inverzne polarizacije. Teorijski rezultati su konzistentni sa postojećim eksperimentalnim podacima za prostornu strukturu pražnjenja i za karakteristike pražnjenja napona/struje.
