Abstract :
The negative corona in SF6 is numerically simulated with a simple one-dimensional model that combines the basic aspects of the physics and chemistry of the electrical discharge. The chemical kinetics model includes charged and neutral species, and particular attention is paid to the generation of S2F10 by the electrical discharge. The role of the electrode walls on the decomposition of S2F10 is investigated as well.
